Timing Properties of Shocked Accretion Flows around Neutron Stars -- II. Viscous Disks and Boundary Layers
Ayan Bhattacharjee, Sandip K. Chakrabarti
We use Smoothed Particle Hydrodynamics to study viscous accretion flows around a weakly magnetic neutron star. We show the formation of multiple ``boundary" layers in presence of b…
Spectral Analysis of Class Data of GRS 1915+105 Using TCAF Solution
Anuvab Banerjee, Ayan Bhattacharjee, Dipak Debnath +1
The class variable source GRS 1915+105 exhibits a wide range of time variabilities in time scales of a few seconds to a few days. Depending on the count rates in different energy b…
Constraining Mass of Cygnus X-1 from Analysis of the Hard State Spectral Data using TCAF Solution
Indrani Banerjee, Ayan Bhattacharjee, Anuvab Banerjee +2
The galactic black hole candidate Cygnus X-1, one of the brightest sources in the sky, is the first ever black hole candidate to be discovered. Despite being a very well-studied ob…
Timing Properties of Shocked Accretion Flows around Neutron Stars in Presence of Cooling
Ayan Bhattacharjee, Sandip K. Chakrabarti
We carry out the first robust numerical simulation of accretion flows on a weakly magnetized neutron star using Smoothed Particle Hydrodynamics (SPH). We follow the Two-Component A…
Generalized Flows around Neutron Stars
Ayan Bhattacharjee
In this chapter, we present a brief and non-exhaustive review of the developments of theoretical models for accretion flows around neutron stars. A somewhat chronological summary o…
Monte Carlo Simulations of Thermal Comptonization Process in a Two Component Advective Flow around a Neutron Star
Ayan Bhattacharjee, Sandip K. Chakrabarti
We explore spectral properties of a Two-Component Advective Flow (TCAF) around a neutron star. We compute the effects of thermal Comptonization of soft photons emitted from a Keple…
