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.

The European Physical Journal C, 2012 From an analogy with non-relativistic degenerate QED plasma we make an estimate of the coupling strength of QGP hypothesized to be present in compact star interiors. At densities ranging from 3ρ 0–10ρ 0 (normal nuclear density ρ 0=0.16 fm−3), quark matter is found to be strongly to intermediately coupled.

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 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.

, 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.

From quark drops to quark stars [PDF]
The European Physical Journal A, 2016 We review some recent results about the mechanism of deconfinement of hadronic matter into quark matter in cold neutron stars and protoneutron stars. We discuss the role of finite size effects and the relevance of temperature and density fluctuations on the nucleation process. We also examine the importance of surface effects for mixed phases in hybrid

STAR highlights on heavy ion physics
EPJ Web of Conferences, 2015 RHIC-STAR is a mid-rapidity collider experiment for studying high energy nuclear collisions. The main physics goals of STAR experiment are 1) studying the properties of the strongly coupled Quark Gluon Plasma 2) explore the QCD phase diagram structure ...

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 ...

ESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

Phase Structure of Compact Star in Modified Quark-Meson Coupling Model
, 2007 The K$^-$ condensation and quark deconfinement phase transitions are investigated in the modified quark-meson coupling model. It is shown that K$^-$ condensation is suppressed because of the quark deconfinement when $B^{1/4}$1.68M$_{\odot}$ is confirmed,
