Quark Models and Radial Oscillations: Decoding the HESS J1731-347 Compact Object's Equation of State
Ishfaq Ahmad Rather, Grigoris Panotopoulos, Ilídio Lopes
We investigate the peculiar nature of strange stars through an analysis of different quark models, i.e. vBag model and CFL model equation of states at different parameter sets, and…
Axion spectra and the associated x-ray spectra of low-mass stars
Ilídio Lopes
For the first time, we predict the axion spectra and their associated luminosities for several low-mass stars -- one and two solar masses stars in the main sequence and post-main s…
QCD color superconductivity in compact stars: color-flavor locked quark star candidate for the gravitational-wave signal GW190814
Zacharias Roupas, Grigoris Panotopoulos, Ilidio Lopes
At sufficiently high densities and low temperatures matter is expected to behave as a degenerate Fermi gas of quarks forming Cooper pairs, namely a color superconductor, as was ori…
Neutron stars: new constraints on asymmetric dark matter
O. Ivanytskyi, V. Sagun, I. Lopes
We study an impact of asymmetric dark matter on properties of the neutron stars and their ability to reach the two solar masses limit, which allows us to present a new range of mas…
The induced surface tension contribution for the equation of state of neutron stars
Violetta V. Sagun, Ilidio Lopes, Aleksei I. Ivanytskyi
We apply a novel equation of state (EoS) that includes the surface tension contribution induced by interparticle interaction and asymmetry between neutrons and protons, to the stud…
Neutron stars: A novel equation of state with induced surface tension
Violetta V. Sagun, Ilidio Lopes
A novel equation of state with the surface tension induced by particles' interactions was generalized to describe the properties of the neutron stars (NSs). In this equation the in…
