Astrophysics with Compact Objects: An Indian Perspective, Present Status and Future Vision
Manjari Bagchi, Prasanta Bera, Aru Beri +18
Astrophysical compact objects, viz., white dwarfs, neutron stars, and black holes, are the remnants of stellar deaths at the end of their life cycles. They are ideal testbeds for v…
On Disk Formation around Isolated Black Holes via Stream Accretion
Priyesh Kumar Tripathi, Indranil Chattopadhyay, Raj Kishor Joshi
We investigate accretion onto an isolated black hole from uniform winds. If the winds are directed towards the black hole, then the accretion process can be well described by the c…
Numerical Simulation of Radiatively driven Transonic Relativistic Jets
Raj Kishor Joshi, Indranil Chattopadhyay, Antonios Tsokaros +1
We perform the numerical simulations of axisymmetric, relativistic, optically thin jets under the influence of the radiation field of an accretion disk. We show that starting from…
Oscillating shocks in the transonic, viscous, variable , accretion flows around black holes
Sanjit Debnath, Indranil Chattopadhyay, Raj Kishor Joshi
We investigate the time evolution of the transonic-viscous accretion flow around a non-rotating black hole. The input parameters used for the simulation are obtained from semi-anal…
