Reversals of toroidal magnetic field in local shearing box simulations of accretion disc with a hot corona
Nishant K. Singh, Arunima Ajay, S R Rajesh
Presence of a hot corona above the accretion disc can have important consequences for the evolution of magnetic fields and the Shakura-Sunyaev (SS) viscosity parameter in such…

Understanding spectral states of sub-Keplerian accretion discs around compact objects as transitions between steady states
Arunima Ajay, S R Rajesh, Nishant K. Singh
We present here a simple hydrodynamic model based on a sequence of steady states of the inner sub-Keplerian accretion disc to model its spectral states. Correlations between differ…
