Hyperonic compact stars with vector portal dark matter

Prafulla K. Panda, Deepak Kumar, Hiranmaya Mishra +1

The appearance of hyperons in the core of neutron stars generally softens the equation of state (EOS), posing a longstanding challenge to the existence of observed two-solar-mass c…

Effects of dark matter and magnetic field on neutron star properties in relativistic mean-field theory: A single-fluid approach

Neeshu Rani, M. Mishra, Deepak Kumar +1

Neutron stars, due to their extremely high matter density and strong magnetic field, provide the best environment for exploring new physics beyond the Standard Model of particle ph…

Neutron star with dark matter using vector portal

Deepak Kumar, Ranjita K. Mohapatra, Hiranmaya Mishra +1

Compact astrophysical objects, such as neutron star, can provide a unique environment where the interplay between strongly interacting nuclear matter and dark matter (DM) can yield…

Constraints on maximum neutron star mass from proto-neutron star evolution

Deepak Kumar, Tuhin Malik, Hiranmaya Mishra +1

A proto-neutron star (PNS) gets formed after a successful supernova when the stellar remnant decouples from the ejecta. In this study, we explore a relativistic framework for the f…

Axion effects on the non-radial oscillations of neutron stars

Deepak Kumar, Hiranmaya Mishra

The effects of axions on quark matter equation of state (EOS) is studied within the three flavor Nambu--Jona-Lasinio model and its effects on on the non-radial oscillations of neut…

CP violation in cold dense quark matter and axion effects on the non-radial oscillations of neutron stars

Deepak Kumar, Hiranmaya Mishra

Charge-conjugation and parity violation in strong interaction for cold dense quark matter is studied with axions of quantum chromodynamic within the three flavor Nambu--Jona-Lasini…

Modification of the universal relation between mass, radius and nonradial -mode oscillation in proto-neutron stars

Deepak Kumar, Asit Karan, Anshuman Verma +2

Neutron stars are usually assumed to be cold; however, in certain dynamical astrophysical scenarios such as newly born neutron stars or binary star mergers, the temperature effects…

The footprint of nuclear saturation properties on the neutron star mode oscillation frequencies: a machine learning approach

Deepak Kumar, Tuhin Malik, Hiranmaya Mishra

We investigate the intricate relationships between the non-radial \(f\) mode oscillation frequencies of neutron stars (NS)s and the corresponding nuclear matter equation of state (…

Robust universal relations in neutron star asteroseismology

Deepak Kumar, Tuhin Malik, Hiranmaya Mishra +1

The non-radial oscillations of the neutron stars (NSs) have been suggested as a useful tool to probe the composition of neutron star matter (NSM). With this scope in mind, we consi…
