Nuclear Physics of Binary Neutron Star Mergers
Armen Sedrakian
Binary neutron star mergers provide a unique laboratory for studying matter under conditions that cannot be reproduced in terrestrial experiments. They probe dense matter at supran…
Bayesian inferences on covariant density functionals from multimessenger astrophysical data: Influences of parametrizations of density dependent couplings
Guo-Jun Wei, Jia-Jie Li, Armen Sedrakian +3
Covariant density functionals have been successfully applied to the description of finite nuclei and dense nuclear matter. These functionals are often constructed by introducing de…
Impact of positrons on electrical conductivity of hot and dense astrophysical plasma
Tigran Petrosyan, Arus Harutyunyan, Armen Sedrakian
We study the influence of positrons on the outer crusts of neutron stars and the interiors of white dwarfs, introducing them as a novel component in both the composition of matter…
Thermoelectric coefficients of two-flavor quark matter from the Kubo formalism
Harutyun Gabuzyan, Arus Harutyunyan, Armen Sedrakian
The hot quark matter created in heavy-ion collision experiments can exhibit strong temperature and chemical-potential gradients, which in turn can generate electric fields through…
Rapidly rotating hot nuclear and hypernuclear compact stars: integral parameters and universal relations
Stefanos Tsiopelas, Armen Sedrakian, Micaela Oertel
In this work, we investigate hot, isentropic compact stars in the limiting cases of static and maximally rotating configurations, focusing on how variations in the symmetry energy…
Topology of the Superconducting Heart of Neutron Stars: Effects of Microphysics and Gravitational-Wave Signatures
Mayusree Das, Armen Sedrakian, Banibrata Mukhopadhyay
We present a general-relativistic study of the distribution of proton superconductivity in strongly magnetized neutron stars (NSs), using the XNS code to solve the coupled Einstein…
