Quark deconfinement and neutrino trapping in compact stars
, 2004 We study the role played by neutrino trapping on the hadron star (HS) to quark star (QS) conversion mechanism proposed recently by Berezhiani and collaborators.

Quark-hybrid matter in the cores of massive neutron stars [PDF]
, 2012 Using a nonlocal extension of the SU(3) Nambu-Jona Lasinio model, which reproduces several of the key features of Quantum Chromodynamics, we show that mixed phases of deconfined quarks and confined hadrons (quark-hybrid matter) may exist in the cores of ...

Cooling Evolution of Hybrid Stars
, 2005 The cooling of compact isolated objects for different values of the gravitational mass has been simulated for two alternative assumptions. One is that the interior of the star is purely hadronic and second that the star can have a rather large quark core.

Thermal Evolution and Light Curves of Young Bare Strange Stars [PDF]
, 2002 The cooling of a young bare strange star is studied numerically by solving the equations of energy conservation and heat transport for both normal and superconducting strange quark matter inside the star.

Generic Conditions for Stable Hybrid Stars
EPJ Web of Conferences, 2014 We study the mass-radius curve of hybrid stars, assuming a single first-order phase transition between nuclear and quark matter, with a sharp interface between the quark matter core and nuclear matter mantle.

Quark-Novae in massive binaries : a model for double-humped, hydrogen-poor, superluminous Supernovae
, 2015 LSQ14bdq and SN 2006oz are super-luminous, hydrogen-poor, SNe with double-humped light curves. We show that a Quark-Nova (QN; explosive transition of the neutron star to a quark star) occurring in a massive binary, experiencing two Common Envelope (CE ...

Constant entropy hybrid stars: a first approximation of cooling evolution [PDF]
, 2017 We aim to 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. We also discuss the strange quark matter stability in the quark matter

, 2013 Neutron stars and quark stars are not only characterized by their mass and radius, but also by how fast they spin, through their moment of inertia, and how much they can be deformed, through their Love number and quadrupole moment.

Effect of color superconductivity on the mass and radius of a quark star [PDF]
, 2007 We compare quark stars made of color-superconducting quark matter to normal-conducting quark stars. We focus on the most simple color-superconducting system, a two-flavor color superconductor, and employ the Nambu-Jona-Lasinio (NJL) model to compute the ...
