Astrometric excess noise in Gaia EDR3 and the search for X-ray binaries
P. Gandhi, D. A. H. Buckley, P. A. Charles +6
Astrometric noise (AEN) in excess of parallax and proper motion is a potential signature of orbital wobble of individual components in binary star systems. The combination of X-ray…
Estimation of the black hole spin in LMC X-1 using AstroSat
Sneha Prakash Mudambi, A. Rao, S. B. Gudennavar +2
LMC X-1, a persistent, rapidly rotating, extra-galactic, black hole X-ray binary (BHXB) discovered in 1969, has always been observed in its high soft state. Unlike many other BHXBs…
Orbital period dependent spatial scatter of Galactic Black Hole Transients
P. Gandhi, A. Rao, P. A. Charles +4
There remain significant uncertainties in the origin and evolution of black holes in binary systems, in particular regarding their birth sites and the influence of natal kicks. The…
Kinematic study of the association Cyg OB3 with Gaia DR2
Anjali Rao, Poshak Gandhi, Christian Knigge +3
We study the stellar kinematic properties and spatial distribution of the association Cyg OB3 using precise astrometric data from Gaia DR2. All known O- and B-type stars in Cyg OB3…
A stochastic propagation model to the energy dependent rapid temporal behaviour of Cygnus X-1 as observed by AstroSat in the hard state
Bari Maqbool, M. Sneha Prakash, R. Misra +8
We report the results from analysis of six observations of Cygnus X-1 by Large Area X-ray Proportional Counters (LAXPC) and Soft X-ray Telescope (SXT) on-board AstroSat, when the s…
Effect of magnetic flux advection on the dynamics of shock in accretion flow around a rotating black hole
Biplob Sarkar, Anjali Rao
We investigate the dynamical behaviour of a magnetized, dissipative, accretion flow around a rapidly rotating black hole. We solve the magnetohydrodynamic equations and calculate t…
