Systematics from NICER Pulse Profiles Drive Uncertainty in Multi-Messenger Inference of the Neutron Star Equation of State
Bhaskar Biswas, Prasanta Char
We present new constraints on the neutron star equation of state (EOS) and mass distribution using a unified Bayesian inference framework that incorporates latest NICER measurement…
Stellar properties indicating the presence of hyperons in neutron stars
Andreas Bauswein, Aristeidis Nikolaidis, Georgios Lioutas +7
We describe distinctive stellar features indicating the presence of hyperons in neutron stars as compared to purely nucleonic systems. A strongly negative curvature of the mass-rad…
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…
Speed of sound in dense matter and two families of compact stars
Silvia Traversi, Prasanta Char, Giuseppe Pagliara +1
The existence of massive compact stars implies that the conformal limit of the speed of sound is violated if those stars have a crust of ordi…
GW190814: On the properties of the secondary component of the binary
Bhaskar Biswas, Rana Nandi, Prasanta Char +2
We show that the odds of the mass-gap (secondary) object in GW190814 being a neutron star (NS) improve if one allows for a stiff high-density equation of state (EoS) or a large spi…
