Abstract

Importance of magnetic fields and gravitational effects, particularly the general relativistic one, is already understood to play key roles in many modern astrophysical processes including underlying gas dynamics. However, in certain features lying with the detection of black holes and white dwarfs, the combined effect of magnetic fields and general relativity appears to be indispensable. They are powerful jets in a black hole accretion disk, ultra-luminous X-ray sources in their hard states, super-Chandrasekhar limiting mass white dwarfs to explain extremely over-luminous type Ia supernovae significantly violating the Chandrasekhar-limit and Philips relation, massive neutron stars predicted by gravitational wave astronomy etc. I will attempt to uncover the key features of the combined magnetic and general relativistic effects, explaining the above stated enigmatic sources observationally.
