Thermal Radiation from Compact Objects in Curved Space-Time

Abhas Mitra, Krishna Kumar Singh

We highlight here the fact that the distantly observed luminosity of a spherically symmetric compact star radiating thermal radiation isotropically is higher by a factor of $(1+z_{…

Mass of Schwarzschild Black Holes Is Indeed Zero And Black Hole Candidates Are Quasi Black Holes

Abhas Mitra

A Schwarzschild Black Hole (BH) is the gravitational field due to a neutral point mass, and it turns out that the gravitational mass of a neutral point mass: (Arnowitt, Deser…

Macroscopic form of the first law of thermodynamics for an adiabatically evolving non-singular self-gravitating fluid

Abhas Mitra

We emphasize that the pressure related work appearing in a general relativistic first law of thermodynamics should involve {\em proper volume element} rather than coordinate volume…

The fallacy of Oppenheimer Snyder Collapse: no general relativistic Collapse at all, no black hole, no physical singularity

Abhas Mitra

By applying Birkhoff's theorem to the problem of the general relativistic collapse of a uniform density dust, we directly show that the density of the dust even when its prop…

No uniform density star in general relativity

Abhas Mitra

As per general relativity (GR), there cannot be any superluminal propagation of energy. And thus, the sound speed in a continuous medium, , must be subluminal. Ho…

Quantum Information Paradox: Real or Fictitious?

Abhas Mitra

One of the outstanding puzzles of theoretical physics is whether quantum information indeed gets lost in the case of Black Hole (BH) evaporation or accretion. Let us recall that Qu…
