Mass-radius relation of strongly magnetized white dwarfs
Prasanta Bera, Dipankar Bhattacharya
We study the strongly magnetized white dwarf configurations in a self-consistent manner as a progenitor of the over-luminous type-Ia supernovae. We compute static equilibria of whi…
Quasi-periodic oscillations from post-shock accretion column of polars
Prasanta Bera, Dipankar Bhattacharya
A set of strongly magnetized accreting white dwarfs (polars) shows quasi-periodic oscillations (QPOs) with frequency about a Hz in their optical luminosity. These Hz-frequency QPOs…
Observing Compact Stars with AstroSat
Dipankar Bhattacharya
This article presents a brief description of India's AstroSat mission which is a powerful space based observatory for compact star research. An account is given of observational co…
Paving the way to simultaneous multi-wavelength astronomy
M. J. Middleton, P. Casella, P. Gandhi +49
Whilst astronomy as a science is historically founded on observations at optical wavelengths, studying the Universe in other bands has yielded remarkable discoveries, from pulsars…
A precise measurement of the orbital period parameters of Cygnus X-3
Yash Bhargava, A. R. Rao, K. P. Singh +9
We present X-ray light curves of Cygnus X-3 as measured by the recently launched AstroSat satellite. The light curve folded over the binary period of 4.8 hours shows a remarkable s…
Surprise in simplicity: an unusual spectral evolution of a single pulse GRB 151006A
R. Basak, S. Iyyani, V. Chand +4
We present a detailed analysis of GRB 151006A, the first GRB detected by Astrosat CZT Imager (CZTI). We study the long term spectral evolution by exploiting the capabilities of \em…
