Abstract :

We know that space is filled with plasma. At the same time, it is also filled with magnetic fields that originate from different sources e.g., stars, accretion disk of black holes, neutron stars, white dwarfs, etc. The astrophysical flows (accretion, wind, jets) occur around or from these objects. Therefore, it is important to include the effects of the magnetic field and study the dynamics of these flows in the magnetohydrodynamic regime. In these flows, the temperature is very high near the base ~ 10^10-11K. So, we need to consider an equation of state (EoS) that can describe accurately the thermodynamics of the flow for each temperature. Also, the mass of the constituent species determines whether a flow is relativistic or non-relativistic. Thus we use an EoS for multispecies flow with variable adiabatic index. In this talk, I will discuss my thesis work in brief and the research projects that I intend to carry out during my post thesis period. The projects I will be focusing on are: (1) two-temperature flows onto the neutron stars and white dwarfs, (2) non-equatorial outflows from the magnetized star or accretion disk, and (3) relativistic magnetized outflows with gravity.
