Nuclear matter at finite temperature and static properties of proto-neutron star

D Sen - Journal of Physics G: Nuclear and Particle Physics, 2020 - iopscience.iop.org
With the effective chiral model, the finite temperature properties of nuclear matter have been
studied at different temperatures. For symmetric nuclear matter, I particularly focused on the …

Could the low‐braking‐index pulsar PSR J1734–3333 evolve into a magnetar?

ZF Gao, N Wang, H Shan - Astronomische Nachrichten, 2017 - Wiley Online Library
The low braking index pulsar PSR J1734− 3333 could be born with a superhigh internal
magnetic field of 1014–1016 G, and undergo a supercritical accretion soon after its …

Thermodynamic Nexus: Investigating the Effect of Temperature and Entropy on the Properties of Neutron Stars with realistic EoS
