Systematic study of the morphology and length of slow stable hybrid star branches
Mauro Mariani, Milva G. Orsaria, Germán Lugones +1
We introduce and systematically study the length of the slow stable hybrid star branch as a quantitative measure of the extended stability region that arises in hybrid neutron star…
Towards a unified hadron-quark equation of state for neutron stars within the relativistic mean-field model
Marcos O. Celi, Mauro Mariani, Milva G. Orsaria +2
The equation of state of dense matter remains a central challenge in astrophysics and high-energy physics, particularly at supra-nuclear densities where exotic degrees of freedom l…
Self-bound quark stars with a first-order two-to-three flavor phase transition
G. Teruya, G. Lugones, A. G. Grunfeld
We investigate self-bound quark stars in a flavor-dependent quark-mass density-dependent model with an excluded-volume correction. We chart the parameter space at zero pressure to…
Sub-GeV dark matter in neutron stars: halo morphologies and their suppression by vacuum-like pressure
Loreany F. Araújo, Germán Lugones, José Ademir S. Lima
We investigate neutron stars that contain a unified dark sector composed of cold, degenerate fermionic dark matter and a vacuum-like dark-energy component. Within a general-relativ…
