On the Maximum Energy Release from Formation of Static Compact Objects

A. Mitra, K. K. Singh

Type II Supernova 1987A (SN 1987A), observed in 1987, released an energy of \mbox{ erg}}. This huge energy is essentially the magnitude of gravitational…

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_{…

How to distinguish an actual astrophysical magnetized black hole mimicker from a true (theoretical) black hole

A. Mitra, C. Corda, H. J. Mosquera Cuesta

We remind that the ring down features observed in the LIGO GWs resulted from trembling of photon spheres (Rp=3M) of newly formed compact objects and not from the trembling of their…

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…
