General-relativistic structure of two-component quantum dark fermion stars
IlÃdio Lopes, Ilídio Lopes
We develop a general-relativistic framework for two-component quantum dark fermion stars: equilibrium configurations of two degenerate fermion species governed by gravity, a Yukawa…
Self-gravitating quantum stars with a globally relevant Bohm potential
Ilidio Lopes
The microphysics underlying non-baryonic dark matter remains unknown. I derive the two-species Schrödinger-Poisson-Yukawa system for spin-1/2 dark-sector fermion fields, (mas…
Color-superconducting quarkyonic matter
Christoph Gärtlein, Oleksii Ivanytskyi, Violetta Sagun +1
We explore the role of color superconductivity in quarkyonic matter under the conditions of color and electric neutrality at - and strong equilibrium, as relevant for neutron s…
Rapidly Spinning Massive Pulsars as an Indicator of Quark Deconfinement
Christoph Gärtlein, Violetta Sagun, Oleksii Ivanytskyi +2
We study rotating hybrid stars, with particular emphasis on the effect of spin on the deconfinement phase transition and star properties. Our analysis is based on a hybrid equation…
Radial Oscillations in Hybrid Stars with Slow Quark Phase Transition
Ishfaq Ahmad Rather, Kauan D. Marquez, Betânia C. Backes +2
This study investigates the radial oscillations of hybrid neutron stars, characterized by a composition of hadronic external layers and a quark matter core. Utilizing a density-dep…
