Solar Physics
Studies on steady and time dependent parts of internal rotation and magnetic field; helioseismology- solar seismic model and nuetrino fluxes; studies on rotation rates of sunspot groups; long period (order of days) global quiet coronal oscillations/waves.
Solar Terrestrial Physics
Effects of solar cycle and activity phenomena on the Indian Monsoon Rainfall and Climate.
Planetary sciences
Precession of the planets and relation to their global magnetic field generated and maintained by dynamo.
Stellar physics
Studies on steady and time dependent parts of internal rotation and magnetic field for the objects on the main sequence, white dwarfs, etc.,
Cosmic Gamma Ray Bursts
Mainly on the source of energy for the central engine which triggers gamma ray bursts
