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…

Non-occurrence of Trapped Surfaces and Black Holes in Spherical Gravitational Collapse

Abhas Mitra

We point out that although the pioneering work of Oppenheimer and Snyder (OS), technically, indicated the formation of an event horizon for a collapsing homogeneous dust ball of ma…

On the true energy budget of GRB970508 and 981214

Abhas Mitra

We emphasize a that since GRB970508 released an energy of Q_g~10^{51} Ωergs in soft gamma rays alone, the actual energy of the e^+e^- p FB driving the blast wave could be considera…

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…
