  • Infrared study of the first identified helium nova V445 Puppis 
    Ashok, N. M (Astronomical Society of India, 2005-06)
    The eruptive variable V445 Puppis has been proposed by us as the first observed Helium nova. The absence of hydrogen lines in the early optical spectra showed the peculiar nature of this object. We have observed V445 Pup ...
  • Inhibition of convective collapse of solar magnetic flux tubes by radiative diffusion 
    Venkatakrishnan, P (Nature Publishing Group, 1986-07)
    Proctor and Weiss (1982) have indicated that the interaction of convection with a magnetic field leads to an intermittent distribution of magnetic flux. Such a process can lead to 'equipartition fields' of 700 G which ...

  • An Insight into the coupling of CME kinematics in inner and outer corona and the imprint of source regions 
    Majumdar, Satabdwa; Ritesh Patel; Pant, V; Banerjee, D (IOP Publishing, 2021-10-01)
    Despite studying coronal mass ejections (CMEs) for several years, we do not yet have a complete understanding of their kinematics. To this end, it is essential to understand the change in kinematics of the CMEs as they ...
  • Insights into the evolution of symbiotic recurrent novae from radio synchrotron emission: V745 Scorpii and RS Ophiuchi
