Effects of Dynamo-Generated Large-Scale Magnetic Fields on the Surface Gravity () Mode
Rajesh Mondal, Nishant K. Singh
By modelling the upper layers of the Sun in terms of a two-layer setup where a free-surface exists within the computational domain, we numerically study the interaction between the…

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…

Strengthening of the f mode due to subsurface magnetic fields in simulations of convection
G. Kishore, Nishant K Singh, Petri Käpylä +1
Previous studies have found that localized strengthening of the f mode recedes the emergence of active regions on the Sun by one day to three days. To help interpret these observat…
