Two temperature solutions and emergent spectra from relativistic accretion discs around black holes
Shilpa Sarkar, Indranil Chattopadhyay, Philippe Laurent
An accreting system in two-temperature regime, admits multiple solutions for the same set of constants of motion, producing widely different spectra. Comparing observed spectrum wi…

General relativistic two-temperature accretion solutions for spherical flows around black holes
Shilpa Sarkar, Indranil Chattopadhyay
Matter falling onto black holes is hot, fully ionized and has to be necessarily transonic. Since the electrons are responsible for radiative cooling via processes like synchrotron,…
