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…

Could a slow stable hybrid star explain the central compact object in HESS~J1731-347?

Mauro Mariani, Ignacio F. Ranea-Sandoval, Germán Lugones +1

We explore an alternative explanation for the low-mass ultra-compact star in the supernova remnant HESS~J1731-347 using a model-agnostic approach to construct hybrid equations of s…

On the Destabilization of High-Mass Neutron Stars by the Emergence of -Hexaquarks

Marcos O. Celi, Mikhail Bashkanov, Mauro Mariani +4

We study the effects of the first nontrivial hexaquark, (2380), on the equation of state of dense neutron star matter and investigate the consequences of its existence for neu…

Constraining self-interacting fermionic dark matter in admixed neutron stars using multimessenger astronomy

Mauro Mariani, Conrado Albertus, M. del Rosario Alessandroni +3

We investigate the structure of admixed neutron stars with a regular hadronic component and a fraction of fermionic self-interacting dark matter. Using two limiting equations of st…

Simplified Thermal Evolution of Proto-hybrid Stars

M. Mariani, M. Orsaria, H. Vucetich

We study the possibility of a hadron-quark phase transition in the interior of neutron stars, taking into account different schematic evolutionary stages at finite temperature. Fur…
