Gauge-invariant perturbations of relativistic non-perfect fluids in spherical spacetime
David Díaz-Guerra, Conrado Albertus, Prasanta Char +1
Astrophysical compact objects are usually studied using a perfect fluid model. However, in astrophysical processes out-of-equilibrium, dissipative effects become important to descr…
Structural response of neutron stars to rapid rotation and its impact on the braking index
Avishek Basu, Prasanta Char, Rana Nandi
Pulsars are rotating neutron stars that are observed to be slowing down, implying a loss of their rotational energy. There can be several different physical mechanisms involved in…
Compact object of HESS J1731-347 and its implication on neutron star matter
Prasanta Char, Bhaskar Biswas
In this work, we investigate the impact of the possibility of a small, subsolar mass compact star, such as the recently reported central compact object of HESS J1731-347, on the eq…
Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object
Elise M. Sänger, Soumen Roy, Michalis Agathos +16
On May 29, 2023, the LIGO Livingston observatory detected the gravitational-wave signal GW230529_181500 from the merger of a neutron star with a lower mass-gap compact object. Its…
