On the Nature of the Compact Objects in the AGNs
Abhas Mitra
If the cores of Galaxies and AGNs comprise Supermassive Stars (SMSs) (Hoyle and Fowler 1963), nuclear energy generation may not be ignited for masses , an…
A Model for Most Luminous and Long Duration Cosmic Gamma Ray Bursts
Abhas Mitra
We exploit the fact that General Theory of Relativity (GTR) predicts the existence of compact objects having surface gravitational redshift z_s < =z_c=0.615 when the Equation of St…
Maximum Accretion Efficiency in General Theory of Relativity
Abhas Mitra
We derive here the expression for the accretion luminosity, , as seen by a distant inertial observer , for the case of spherical accretion onto a static compac…
Final State of Spherical Gravitational Collapse and Likely Source of Gamma Ray Bursts
Abhas Mitra
Following our result that for the final state of continued spherical gravitational collapse, the gravitational mass of the fluid, , we show that for a physical fluid the…
Towards the Final State of Spherical Gravitational Collapse and Likely Source of Gamma Ray Bursts
Abhas Mitra
We invoke the global properties of the actual GTR field equations for spherical collapse to directly show that the condition for formation of trapped surfaces, 2GM/R >1 is not allo…
Constraining the Magnetic Field in Gamma Ray Burst Blast Waves
Abhas Mitra
We point out that the already existing literature on relativistic collisionless MHD shocks show that the parameter sigma= upstream proper magnetic energy density/upstream rest mass…
