  • Different distribution functions of solar x-ray flares 
    Das, T. K; De, B. K; Bhattacharyya, J (Astronomical Society of India, 2004-03)
    A statistical study has been done on soft x-ray (SXR) flares, the data of which were collected by Geostationary Operational Environmental Satellites (GOES) during the period July 1993?June 1994. From the analysis different ...
  • ECRA dynamic spectrograph - design and test results 
    Chatterjee, T. N; Bera, R; Guha Majumdar, G; Das, T. K; Sen, A. K (Astronomical Society of India, 1998)
    Eastern Centre for Research in Astrophysics (ECRA) set up by the University Grants Commission in 1993, involving Universities and Research Institues of Eastern Region with Calcutta University as the nodal centre, started ...
  • A new cycle in the periodicity of solar flare indices. 
    Das, T. K; Nag, T. K (Astronomical Society of India, 2003)
    A new cycle of about 5.5 years has been invoked in case of the periodicity in solar flare indices. As there exists no instrumental technique for measuring directly the energy output of an optical flare, the energy emitted ...
  • Solar proton events in relation to H-alpha flares 
    Das, T. K; Nag, T. K; Dutta, A. K (Astronomical Society of India, 1998)
    A study has been made about the solar proton events observed by NOAA satellite during the period 1976-1993 by considering their association with Hα-flares. The proton flux has been found to depend linearly upon the estimated ...
  • Studies on Halpha and SXR flares in relation to Type III metric bursts 
    Das, T. K; Sarkar, H; Manna, A (Astronomical Society of India, 2005-03)
    A study was made on Halpha and SXR flares in relation to Type III metric bursts. The interrelationship between Halpha and SXR flares was examined by grouping the events into two categories, (i) the events associated with ...
