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…
Quarkyonic Neutron Stars as Candidates for the GW230529 Mass-Gap Object
Jeet Amrit Pattnaik, S. K. Patra
We examine whether quarkyonic equations of state (EOS) can account for compact objects in the - mass range reported for the GW230529 gravitational-wave event. Th…
Dirac vs. Majorana Dark Matter Imprints on Neutron Star Observables
M. Bhuyan, Jeet Amrit Pattnaik, S. K. Patra +1
The fundamental character of a fermionic dark matter, whether it is a Dirac or Majorana particle remains a key unresolved issue whose answer would profoundly affect dark-sector phe…
-mode oscillation of neutron star in a new relativistic hybrid model
D. Dey, Jeet Amrit Pattnaik, R. N. Panda +1
We investigate how the pulsation frequencies of axial gravitational-wave modes (-modes) in a non-rotating neutron star depend on its composition, particularly when including qua…
