The recent direct observation of gravitational wave event GW170817 and its GRB170817A
signal has opened up a new window to study neutron stars and heralds a new era of …

From quark drops to quark stars: some aspects of the role of quark matter in compact stars

G Lugones - The European Physical Journal A, 2016 - Springer
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 …

Quark deconfinement and implications for the radius and the limiting mass of compact stars

I Bombaci, I Parenti, I Vidana - The Astrophysical Journal, 2004 - iopscience.iop.org
We study the consequences of the hadron-quark deconfinement phase transition in stellar
compact objects when finite-size effects between the deconfined quark phase and the …

Imprints of the nuclear symmetry energy slope in gravitational wave signals emanating from neutron stars

LL Lopes, VBT Alves, COV Flores, G Lugones - Physical Review D, 2023 - APS
We investigate possible traces of the nuclear symmetry energy slope (L) in the gravitational
wave emission of neutron stars. For fixed stellar mass values, we examine how the slope …

Combustion of a neutron star into a strange quark star: The neutrino signal

G Pagliara, M Herzog, FK Röpke - Physical Review D—Particles, Fields …, 2013 - APS
There are strong indications that the process of conversion of a neutron star into a strange
quark star proceeds as a strong deflagration implying that in a few milliseconds almost the …

Magnetized hybrid stars: effects of slow and rapid phase transitions at the quark–hadron interface

M Mariani, MG Orsaria… - Monthly Notices of …, 2019 - academic.oup.com
We study the influence of strong magnetic fields in hybrid stars, composed by hadrons and a
pure quark matter core, and analyse their structure and stability as well as some possible …

Burning of a hadronic star into a quark or a hybrid star

A Drago, A Lavagno, I Parenti - The Astrophysical Journal, 2007 - iopscience.iop.org
We study the hydrodynamical transition from a hadronic star into a quark or a hybrid star. We
discuss the possible mode of burning, using a fully relativistic formalism and realistic …

Numerical simulation of the hydrodynamical combustion to strange quark matter

B Niebergal, R Ouyed, P Jaikumar - Physical Review C—Nuclear Physics, 2010 - APS
We present results from a numerical solution to the burning of neutron matter inside a cold
neutron star into stable u, d, s quark matter. Our method solves hydrodynamical flow …

Relativistic simulations of the phase-transition-induced collapse of neutron stars

EB Abdikamalov, H Dimmelmeier… - Monthly Notices of …, 2009 - academic.oup.com
An increase in the central density of a neutron star may trigger a phase transition from
hadronic matter to deconfined quark matter in the core, causing it to collapse to a more …

Effects of color superconductivity on the nucleation of quark matter in neutron stars

I Bombaci, G Lugones, I Vidana - Astronomy & Astrophysics, 2007 - aanda.org
Aims. We study the nucleation of quark matter drops at the center of cold deleptonized
neutron stars. These drops can be made up of unpaired quark matter or of color …
