  • Bandyopadhyay, A; Sivarani, T; Susmitha, A; Beers, T. C; Giridhar, S; Arun Surya; Masseron, T (IOP Publishing, 2018-06-01)
    SDSS J082625.70+612515.10 (V = 11.4; [Fe/H] = −3.1) and SDSS J134144.60+474128.90 (V = 12.4; [Fe/H] = −3.2) were observed with the SDSS 2.5m telescope as part of the SDSS MARVELS spectroscopic pre-survey and identified ...
  • Bombaci, I; Datta, B (The American Astronomical Society, 2000-02)
    We study the conversion of a neutron star to a strange star as a possible energy source for gamma-ray bursts. We use different recent models for the equation of state of neutron star matter and strange quark matter. We ...
  • Datta, B; Thampan, A. V; Wiita, P. J (Indian Academy of Sciences, 1995-12)
    For accretion on to neutron stars possessing weak surface magnetic fields and substantial rotation rates (corresponding to the secular instability limit), we calculate the disk and surface layer luminosities general ...
  • Roy, Tridib (IOP Publishing, 2023-04)
    Pulsars are believed to be one of the most interesting objects in the universe. The emission mechanism of pulsars is still a conundrum to physicists, as there is no completely acceptable theory that can establish a consensus ...
  • Sahu, P. K; Basu, R; Datta, B (American Astronomical Society, 1993-10-10)
    We present a field theoretical equation of state for nuclear matter and neutron-rich matter in β equilibrium using the chiral sigma model. The model includes an isoscalar vector field generated dynamically and reproduces ...

C (IOP Publishing, 2017-10)
    On 2017 August 17 a binary neutron star coalescence candidate ( later designated GW170817 ) with merger time 12:41:04 UTC was observed through gra vitational waves by the Advanced LIG O and Advanced Virgo detectors. ...
  • Datta, B; Thampan, A. V; Bhattacharya, D (Indian Academy of Sciences, 1995-12)
    An accurate numerical survey of the density profiles corresponding to the crusts of neutron stars for representative equation of state models is presented. This will find application in calculations of thermal and magnetic ...
