Fastest spinning millisecond pulsars: indicators for quark matter in neutron stars?
Christoph Gärtlein, Violetta Sagun, Oleksii Ivanytskyi +2
We study rotating hybrid stars, with a particular emphasis on the effect of a deconfinement phase transition on their properties at high spin. Our analysis is based on a hybrid equ…
Tidal Love numbers of anisotropic stars within the complexity factor formalism
Ãngel Rincón, Grigoris Panotopoulos, IlÃdio Lopes
We compute the quadrupolar gravitoelectric tidal Love numbers of spherical configurations made of anisotropic matter. Anisotropies are introduced within the vanishing complexity fa…
Anisotropic Dark Energy Stars within Vanishing Complexity Factor Formalism: Hydrostatic Equilibrium, Radial Oscillations, and Observational Implications
G. Panotopoulos, A. Rincon, I. Lopes
We investigate the structure and radial oscillations of anisotropic compact stars composed of dark energy, using the vanishing complexity factor formalism within general relativity…
Radial Oscillations of Hybrid Stars and Neutron Stars including Delta baryons: The Effect of a Slow Quark Phase Transition
Ishfaq Ahmad Rather, Kauan D. Marquez, Betania C. Backes +2
We study radial oscillations of hybrid neutron stars composed of hadronic external layers followed by a quark matter core. We employ a density-dependent relativistic mean-field mod…
