Prof BN Dwivedi is an Institute Professor of physics at the Indian Institute of Technology (Banaras Hindu University). He superannuated as Professor (HAG) in May 2015. He has been a research physicist at the University of California, San Diego (1980-81); a royal society visitor at the Glasgow university (1989); Commonwealth Academic Staff Fellow at Glasgow, Cambridge and Oxford (1990-91); a visiting scientist at Max-Planck-Institut für Sonnensystemforschung (MPS), Germany for over 25 years (1991 - 2015).

 He has over thirty-seven years of teaching experience at BTech/MTech level, and broad experience in Solar and Space Plasma Physics, with involvement in almost all the major solar space experiments, including Skylab, Yohkoh, SoHO, TRACE, Hinode, STEREO, SDO, and presently IRIS. He is also a member of ‘Science Working Group’ of ‘Visible Emission Line Coronagraph (VELC)’, and ‘Solar Ultraviolet Imaging Telescope (SUIT)’ for the ISRO's Aditya-L1 mission.

He is an outstanding science teacher at a wide range of levels. He is unusual (almost unique) among science teachers in being simultaneously an active professional research scientist at a high international level. His obvious passion for understanding the mysteries of the Sun (a grand physics laboratory in the sky) is a major motivation for his research on solar phenomena. His deep and wide professional knowledge of these, informs and authenticates his innovative & interactive class lectures, pedagogical and popular expositions. He has supervised 6 PhDs and several projects/dissertations at the BTech/MTech/PhD level.

He has published over 287 research papers, reviews, book chapters, and articles in reputed Indian/International journals/magazines/newspapers (Two research papers with 340 and 268 citations and many more with citations in the range of 20 to 108). He has been honoured with several national and international awards, especifically,  National award for outstanding efforts in science and technology communication (2005); Indian National Science Academy: Indira Gandhi Prize for popularization of science (2011); Popular writing award on solar physics by American Astronomical Society/Solar Physics Division (2004).

 In recognition of his outstanding contributions to the SUMER/SoHO science, of which he has been an Associate Scientist from the non-European countries, he was honored with the prestigious 'MPAE Gold Pin’ in 1999. He has been travelling widely giving invited talks/colloquia at national and international symposia/seminars/colloquia, and also at premier institutions in India and abroad. He is also extensively involved in science communication and pedagogical research.

Prof. Dwivedi has written a cover story feature article in Scientific American (2001) and also in its special issue (2003), guest-edited a solar physics issue of ‘Current Science’ (1999), and his edited book ‘Dynamic Sun’ published by Cambridge University Press (2003, 2007) has received laudatory reviews. He has also edited the book on ‘Physics of the Sun and its Atmosphere’, published by World Scientific, Singapore (2008). His book ‘Lecture Notes on Maxwell's Equations’ has been published by LAMBERT Academic Publishing (2013).

He has coauthored a 'Research News' on "Coronal heating by Alfvén waves" in Current Science (2010) which is cited in Wikipedia on Corona (https://en.wikipedia.org/wiki/Corona).​ Recently, he has co-authored a seminal contribution in a natureresearch journal “Scientific Reports” (2017) which unravels the mystery of ‘coronal heating’. This paper is cited in Wikipedia on Alfvén wave (https://en.wikipedia.org/wiki/Alfvén_wave).

Prof Dwivedi is on the Editorial Board of Scientific Reports – a Nature Research journal. http://www.nature.com/srep/.
 
Most recently, he co-authored a discovery research paper, "Confined pseudo-shocks as an energy source for the active solar corona",

Scientific Achievement: Summary

Dwivedi’s earliest research contributions dating from 1978 are on solar spectra, an old and yet new, but always fertile, field of phyiscs as well as source of physical knowledge about the Sun and the Universe. He has been pursuing commendable research in solar physics for the last over four decades, with his continued involvement in almost all the major solar space experiments, e.g., Skylab, Yohkoh, SoHO, TRACE, RHESSI, Japan’s solar spacecraft Hinode, NASA’s SDO, and now IRIS. His research interests include the Physics and Diagnostics of Solar X-ray and EUV Emission Processes as well as Waves and Oscillations in the Solar Atmosphere. He is an outstanding science Teacher at a wide range of levels. He is unusual (almost unique) among science teachers in being simultaneously an active professional research scientist at a high international level. His obvious passion for understanding the mysteries of the Sun is a major motivation for his research on solar phenomena. His deep and wide professional knowledge of these, informs and authenticates his innovative class lectures, pedagogical and popular expositions. A summary of his scientific achievement is as under:
 
He has made significant contributions to the theory and modeling of solar plasma in optical, ultraviolet, X-ray, gamma-ray, and in atomic spectroscopy – especially in the field of diagnostics of electron and proton beams and of the plasmas they heat. He has also made seminal contributions in the areas of  ‘wave  activity in the solar atmosphere’ and in ‘science communication’. Some of his original contributions include:

(1) Physics and diagnostics of solar EUV and X-ray emission processes: The inference of electron density and temperature structure of astrophysical and laboratory plasmas from diagnostic line ratios is a problem of universal importance. The physical importance of these line diagnostics lies in the influence of density and temperature on the plasma process being considered, whether thermonuclear fusion, transport coefficients, energy transport, magnetic reconnection, particle acceleration, etc. Prof  Dwivedi obtained new results on many spectral line ratio diagnostics, which formed the basis for several observing sequences from the CDS and SUMER instruments onboard the SoHO spacecraft (e.g., Space Sci. Rev. 65, 289-316, 1994;  Astrophys. J. 517, 516-525, 1999). He developed a new density and temperature model of coronal holes which is the best available model to date (Astrophys. J. 500, 1023-1038, 1998). His original findings on the abundance anomaly, FIP-effect in coronal structures, and identification of new emission lines and their potential diagnostic applications have  been highly commended (e.g., Astron.&Astrophys. 364, 835-844, 2000; Astrophys. J. 582, 1162-1171, 2003). He has also made an original contribution to the mathematical formulation of ‘diagnostics of inhomogeneous structures’ (Astron.&Astrophys. 249, 277-283, 1991). The most comprehensive reviews on ‘Physics of ultraviolet emissions: observations and interpretations’ have been published  in two parts (Space Sci. Rev. 111, 415-480, 2004, and Space Sci. Rev.  133, 103-179, 2007). His seminal work on active region loops observed by EIS/Hinode  has been published (Astrophys. J. 694, 1256-1265, 2009).

(2) Physics of solar flares: Prof Dwivedi discovered that the peaks of hard X-ray emission coincide with penetration of the emitting flare loops into penumbrae of sunspots which was a landmark new result at the time in the understanding of  particle acceleration in solar flares (Solar Phys. 90, 331-341, 1984). This research was later confirmed by the SMM spacecraft. His seminal work on gamma-radiation and white-light flares has also been highly commended (Solar Phys. 76, 45-61, 1982). ‘A multi-wavelength study of an M-class flare and the origin of an associated eruption from NOAA AR 11045’ has been published in New Astronomy 17, 542-551 (2012). His most recent work on “Confined Partial Filament Eruption and its Reformation within a Stable Magnetic Flux Rope” has been published in Astrophysical Journal (2014).

(3) Wave activity in the solar atmosphere: Prof Dwivedi’s fundamental contributions (Astron.&Astrophys. 415, 1133-1139, 2004; Astron.&Astrophys. 435, 733-741, 2005) on the emission line broadening, and/or narrowing; and the work on the dissipation of Alfvén waves in the solar wind source region (Solar Phys. 237, 143-152, 2006) have provided new clues to understanding the coronal heating and solar wind acceleration mechanisms. He estimated magnetic field in  spicules using the unique tool of coronal seismology (New Astronomy 12, 479-482, 2007) and explained the spatial damping of compressional MHD waves in prominences through a novel approach of invoking turbulent viscosity (Astron.&Astrophys. 473, 931-936, 2007). New results on the energetics of long-period slow MHD waves in the solar wind source region have been reported (New Astronomy 13, 581-586, 2008). He has also investigated intensity oscillations in the solar chromosphere and the corona which establish the signature of magneto-acoustic wave propagation above the network, proposing that field-free cavity areas under bipolar magnetic canopies, in the vicinity of a magnetic network, most likely serve as resonators for the magneto-acoustic waves (Astron.&Astrophys. Lett. 481, L95-L98, 2008). He detected sausage oscillations in cool post flare loop (Monthly Notices Roy. Astron. Soc. 388, 1899-1903, 2008) and  the first signature of slow accoustic oscillations  in the non-flaring coronal loop (New Astronomy 15, 8-15, 2010). He showed the leakage of 5 min oscillations to be significant for heating the Sun’s atmosphere locally (Monthly Notices Roy. Astron. Soc. 405, 2317-2326, 2010). ‘Observation of intensity oscillations above X-ray bright points (XBPs) from Hinode/XRT: Signature of MHD oscillations in the solar corona’ has been published in Monthly Notices Roy. Astron. Soc. 415, 1419-1425 (2011). He has published a seminal paper on ‘Possible Signature of Alfvén Wave Dissipation in the Localized Magnetic Funnels of  the Equatorial Solar Corona’ in Publications of the Astronomical Society of Japan (PASJ), 66 (SP1), S13 (1–11) (2014). Most recently, he published a paper on ‘Magnetohydrodynamic Seismology of a Coronal Loop System by the First Two Modes of Standing Kink Waves’ in Astrophysical Journal  799, 151, 10 pages (2015).

(4) Physics of red/blue shifted emission in the Sun’s atmosphere:  Prof  Dwivedi  has been  investigating the physics of red- and /or blue-shifted emission in the Sun’s atmosphere. His work on the redshifted footpoints of coronal loops (Annales Geophysicae 26, 2955-2959, 2008 and the redshifted network contrast of transition region emission (Astron.&Astrophys. Lett. 491, L13-L16, 2008) seem to be a direct consequence of the prevailing global mass transport in the Sun’s atmosphere.

(5) An impact model of Newton's law of gravitation: Gravity, massive particles, photons and Shapiro delay: The far-reaching gravitational force, in the approximation of Newton's law of gravitation, is described by a heuristic model with hypothetical massless particles propagating at the speed of light in vacuum and transferring momentum and energy between physical entities through interactions on a local basis. Objections raised against this idea are dispelled by invoking the Special Theory of Relativity, considering non-local interactions, and replacing the shielding concept by a secular mass increase of massive bodies. This impact model of gravity is applied to particles with relative motions at slow and relativistic speeds. Based on this model, a gravitational interaction mode is then conceived between photons and massive particles. This implies a deflection perpendicular to the propagation direction of a photon twice as large as expected from the mass-energy relation of photons, in accordance with observations and the General Theory of Relativity. The longitudinal interaction is compatible with the energy and momentum conservation principles applied to massless entities, and the results are consistent with the observed Shapiro delay (Astrophys. Space Sci. 343, 135-144, 2013; Astrophys. Space Sci.  343, 145-151, 2013).

In addition, his seminal contributions on “On the gravitational redshift”, “Secular perihelion advances of the inner planets and asteroid Icarus”,“Photon in a cavity -- a Gedankenexperiment”, and “On the potential energy in a gravitationally bound two-body system” have been published in New Astronomy 31, 8-13 (2014); 31, 51-55 (2014); 34, pages 211-216 (2015); and 34, pages 250-252 (2015)  respectively while Anomalous Earth flybys of spacecraft” in Astrophys. Space Sci. 358:18, 8 pages (2015).

(6) Science Communication:

     The most prominent contribution here is the first cover story feature article on ‘The Paradox of the Sun’s Hot Corona’ in the June 2001 issue of Scientific American, which was so greatly appreciated that its updated version has been republished in the Scientific American special edition, in 2003. Some of his latest articles include:  ‘Will the Sun Storm Today?’ in the April 2006 issue of Astronomy Now (a leading UK magazine), ‘Blowing in the Supersonic Wind’ in the April 2007 issue of Scientific American India, ‘Lightning on Venus’ in the March 2008  issue of Science Reporter, ‘What makes the Sun shine?’  in the November 2010 issue of Science Reporter, ‘Coronal Heating by Alfvén Waves’ in Current Science (2010) etc.

In a major effort to motivate young minds in colleges and universities towards space science, he organized a National Workshop in November 2006 at Meerut College. Consequently, a pedagogical-updated-modern view of “Physics of the Sun and its Atmosphere” in the form of a Book has been published  by World Scientific, Singapore (2008). He organized an interactive seminar on the total solar eclipse (TSE) in Varanasi on 21 July 2009 at IT-BHU. On the Eclipse Day (22 July 2009), he observed the Sun from an eclipse science camp at the Saamne Ghat, Varanasi and educated thousands of people.
