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…
How Neutron Star Observations Point Towards Exotic Matter: Existing Explanations and a Prospective Proposal
Mauro Mariani, Ignacio F. Ranea-Sandoval
Multi-messenger astronomical observations of neutron stars, together with more precise calculations and constraints coming from dense matter microphysics, are generating tension wi…
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…
Exploring the role of hexaquarks on quark deconfinement and hybrid stars
Marcos O. Celi, Mauro Mariani, Rajesh Kumar +5
We investigate the impact of the (2380) hexaquark on the equation of state (EoS) of dense matter within hybrid stars (HSs) using the Chiral Mean-Field model (CMF). The hexaqua…
Consistent crust-core interpolation and its effect on non-radial neutron star oscillations
Martin O. Canullan-Pascual, Mauro Mariani, Ignacio F. Ranea-Sandoval +2
To model the structure of neutron stars (NSs) theoretically,it is common to consider layers with different density regimes. Matching the equation of state (EoS) for the crust and c…
