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…
The Delta-isobar masquerade: intrahadronic phase transitions and their quark-mimicking signatures in neutron stars
Martin O. Canullan-Pascual, Germán Lugones, Ignacio F. Ranea-Sandoval +1
We investigate the conditions under which isobars trigger a first-order phase transition within purely hadronic neutron-star matter, using the SW4L relativistic mean-fie…
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…
Fast Pulsars, Neutron Stars, and Astrophysical Strange Quark Matter Objects
Delaney Farrell, Fridolin Weber, Milva G. Orsaria +5
This book chapter explores key aspects of neutron stars, pulsar glitches, tidal deformability, fast pulsars, the equation of state, and strange quark matter stars. Challenges in di…
