  • Evolution of rotating 25 M Population III star: physical properties and resulting supernovae 
    Aryan, Amar; Pandey, Shashi Bhushan; Gupta, Rahul; Ror, Amit Kumar (Monthly Notices of the Royal Astronomical Society Letters, 2023-05)
    In this letter, we report the outcomes of 1D modelling of a rotating 25 M zero-age main sequence Population III (Pop III) star up to the stage of the onset of core collapse. Rapidly rotating models display violent and ...
  • Modeling the late-time merger ejecta emission in short gamma ray bursts 
    Ghosh, Ankur; Misra, Kuntal, et.al.; Omar, Amitesh; Panchal, Dimple (Journal Astrophysical Astronomy, 2022-12)
    The short gamma ray bursts (GRBs) are the aftermath of the merger of binary compact objects (neutron star–neutron star or neutron star–black hole systems). With the simultaneous detection of gravi tational wave (GW) signal ...
  • Search for merger ejecta emission from late-time radio observations of short GRBs using GMRT 
    Ghosh, Ankur; Vaishnava, C. S.; Resmi, L.; Misra, Kuntal; Arun, K. G.; Omar, Amitesh; Chakradhari, N. K. (Monthly Notices of the Royal Astronomical Society, 2024-01)
    In some cases, the merger of two neutron stars can produce a rapidly rotating and highly magnetized millisecond magnetar. A significant proportion of the rotational energy deposited to the emerging ejecta can produce a ...
  • Two-temperature accretion flows around strongly magnetized stars and their spectral analysis 
    Sarkar, Shilpa; Singh, Kuldeep; Chattopadhyay, Indranil; Laurent, Philippe (Monthly Notices of the Royal Astronomical Society, 2023-07)
    We investigate two-temperature accretion flows onto strongly magnetized compact stars. Matter is accreted in the form of an accretion disc upto the disc radius (rd), where, the magnetic pressure exceeds both the gas and ...
