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…
Thermal conduction and thermopower of inner crusts of magnetized neutron stars
Henrik Danielyan, Arus Harutyunyan, Armen Sedrakian
We compute the thermal conductivity and thermoelectric power (thermopower) of the inner crust of compact stars across a broad temperature-density domain relevant for proto-neutron…
Generalized relativistic second-order dissipative hydrodynamics: coupling different rank tensors
Arus Harutyunyan, Armen Sedrakian
In this work, we extend the formalism of second-order relativistic dissipative hydrodynamics, developed previously using Zubarev's non-equilibrium statistical operator formalism. B…
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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
