  • Coronal heating by magnetic kink waves 
    Banerjee, D; Dikpati, M; Choudhuri, A. R (Astronomical Society of the Pacific, 1998)
    We show that the magnetic kink waves generated by the motions of the Photospheric footpoints of the coronal flux tubes can supply adequate energy for heating the quiet corona. We model the solar corona as two-layer isothermal ...
  • Coronal Heating Experiments of the Williams College Group at Mukandgarh Fort, Rajasthan 
    Pasachoff, J. M; Babcock, B. A; Sebastian Diaz; Reardon, K. P; Kutner, E. R (Indian Institute of Astrophysics, Bangalore, 1997)
    We report on the Williams College expedition to Mukandgarh Fort, Rajasthan, for the total solar eclipse of 24 October 1995. The main experiments were a search for 1 Hz oscillations in coronal loops as an indication of ...
  • Modelling of Solar Coronal Oscillations 
    Krishan, V (Indian Institute of Astrophysics, Bangalore, 1997)
    The study of coronal osciallations is important since these oscillations could be responsible for the heating of the solar corona. Coronal structures are ex[ected to undergo three types of oscillations - non-compressional ...
  • On solar coronal heating 
    Pandey, K; Narain, U (Astronomical Society of India, 2001)
    We review heating of solar corona by magnetic fields/currents. Our emphasis is on micro- and nano-flares. In case of a microflare the energy release is ~1026 ergs whereas in a nanoflare ~1023 - 1025 ergs of energy is ...
  • Results of 1995 eclipse observation and observing program for 1998 and 1999 eclipses 
    Singh, J (Astronomical Society of India, 1998)
    We, at the Institute of Astrophysics, conducted ten experiments from two places namely Neem Ka Thana in Rajasthan and Kalpi in Uttar Pradesh. The experiments involved high spatial and spectral resolution spectroscopy to ...
  • Spectroscopic Observation of Oscillations in the Corona During the Total Solar Eclipse of 22 July 2009 
    Singh, J; Hasan, S. S; Gupta, G. R; Nagaraju, K; Banerjee, D (Springer, 2011-05)
    We performed high resolution spectroscopy of the solar corona during the total solar eclipse of 22 July 2009 in two emission lines: the green line at 5303 Å due to Fe xiv and the red line at 6374 Å due to Fe x, simultaneously ...
  • X - ray spectrometers on - board Aditya - L1 for solar flare studies 
    Sankarasubramanian, K; Sudhakar, M; Sudhakar, M; Nandi, Anuj; Ramadevi, M. C; Adoni, A. A; Kushwaha, A; Agarwal, Anil; Dey, A; Joshi, B; Singh, Brajpal||Girish, V; Tomar, I; Majhi, K. K; Kumar; Olekar, Manjunath; Bug, M; Pala, Manohar; Thakur, Mukund Kumar; Badagandi, Rajeev R; Ravishankar, B. T; Garg, Sarthak; Sitaramamurthy, N; Sridhara, N; Umapathy, C. N; Gupta, Vinod Kumar; Agrawal, Vivek Kumar; Yougandar, B (Current Science Association, 2017-04)
    Aditya-L1 mission will carry two high-spectral resolution X-ray spectrometers to study solar flares. The soft X-ray spectrometer will cover the energy range from 1 to 30 keV, while the hard X-ray spectrometer will cover ...
