Parameter Space Study of Magnetohydrodynamic Flows around Magnetized Compact Objects
In recent years, the study of magnetohydrodynamic (MHD) accretion flow around compact objects has become very important since the magnetic field in ubiquitous in the universe and it should play a part in the black hole accretion, especially close to the inner disk. The pioneering works of Mestel (1967) and Weber & Davis (1967) etc. were further extended by Chakrabarti (1990) for rotating compac...
متن کاملPhysics of accretion flows around compact objects
Several physical and astrophysical problems related to accretion onto black holes and neutron stars are shortly reviewed. I discuss the observed differences between these two types of compact objects in quiescent Soft X-ray Transients. Then I review the status of various non-standard objects suggested as an alternative to black-holes. Finally I present new results and suggestion about the natur...
متن کاملGeneral relativistic hydrodynamic flows around a static compact object in final stages of accretion flow
Dynamics of stationary axisymmetric configuration of the viscous accreting fluids surrounding a non-rotating compact object in final stages of accretion flow is presented here. For the special case of thin disk approximation, the relativistic fluid equations ignoring self-gravity of the disk are derived in Schwarzschild geometry. For two different state equations, two sets of self-consistent an...
متن کاملTransonic properties of the accretion disk around compact objects
An accretion flow is necessarily transonic around a black hole. However, around a neutron star it may or may not be transonic, depending on the inner disk boundary conditions influenced by the neutron star. I will discuss various transonic behavior of the disk fluid in general relativistic (or pseudo general relativistic) framework. I will address that there are four types of sonic/critical poi...
متن کاملLense-thirring Precession of Accretion Disks around Compact Objects
Misaligned accretion disks surrounding rotating compact objects experience a torque due to the LenseThirring effect, which leads to precession of the inner disk. It has been suggested that this effect could be responsible for some low frequency Quasi-Periodic Oscillations observed in the X-ray lightcurves of neutron star and galactic black hole systems. We investigate this possibility via time-...
