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…

Effect of symmetry energy on properties of rapidly rotating neutron stars and universal relations

Pion Sudarshan Yeasin, Stefanos Tsiopelas, Armen Sedrakian +1

We investigated universal relations for compact stars rotating at the Keplerian (mass-shedding) limit, which is highly relevant for understanding the rapidly rotating objects forme…

Bulk Viscosity of Two-Flavor Color Superconducting Quark Matter in Neutron Star Mergers

Mark Alford, Arus Harutyunyan, Armen Sedrakian +1

This work investigates the bulk viscosity of warm, dense, neutrino-transparent, color-superconducting quark matter, where damping of density oscillations in the kHz frequency range…

Bulk viscosity of two-color superconducting quark matter in neutron star mergers

Mark Alford, Arus Harutyunyan, Armen Sedrakian +1

We study the bulk viscosity of moderately hot and dense, neutrino-transparent color superconducting quark matter arising from weak-interaction-driven direct URCA processes. The qua…

Finite-temperature equations of state of compact stars with hyperons: three-dimensional tables

Stefanos Tsiopelas, Armen Sedrakian, Micaela Oertel

We construct tables of finite temperature equation of state (EoS) of hypernuclear matter in the range of densities, temperatures, and electron fractions that are needed for numeric…

Neutron star cooling within the equation of state with induced surface tension

Stefanos Tsiopelas, Violetta Sagun

We study the thermal evolution of neutron stars described within the equation of state with induced surface tension (IST) that reproduces properties of normal nuclear matter, fulfi…
