  • Ritam Mallick mostly works in the field of Nuclear Astrophysics related to neutron stars (NS's). His main interest is to study the astrophysical phase transition (PT) occurring in NS's. This involves the hydrodynamic evolution of the PT front via shock waves. His research also involves the study of the equation of state (EoS) of the stellar matter and the recent constraints on the masses of NS's.
  • Magnetic (B) field in some stars (Anomalous X-ray pulsars and soft gamma repeaters) is another area of his interest. The magnetic field evolution and the deformation of NS's due to such strong B fields is an open problem. The high density and ultra-strong B fields in NS's can also lead to mesonic condensate in stars. Such astrophysical events of PT and star's deformation due to B fields leads to various observational signatures like gamma-ray bursts and gravitational wave emission which are his current research areas.
