Hot Neutron Star Matter and Proto-Neutron Stars
D. Farrell, A. Alp, W. Spinella +4
In this chapter, we investigate the structure and composition of hot neutron star matter and proto-neutron stars. Such objects are made of baryonic matter that is several times den…
Phases of Hadron-Quark Matter in (Proto) Neutron Stars
F. Weber, D. Farrell, W. M. Spinella +4
In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron…
Phase transitions in neutron stars and their links to gravitational waves
Milva G. Orsaria, Germán Malfatti, Mauro Mariani +6
The recent direct observation of gravitational wave event and its signal has opened up a new window to study neutron stars and heralds a new era of Astronom…
Hyperonic Neutron Star Matter in Light of GW170817
William M. Spinella, Fridolin Weber
Since 2013 the mass of pulsar PSR J0348+0432 () has provided a tight constraint on neutron star equation of state. However, a number of different analyses of t…
Quark Deconfinement in Rotating Neutron Stars
R. D. Mellinger, F. Weber, W. Spinella +2
In this paper, we use a three flavor non-local Nambu--Jona-Lasinio (NJL) model, an~improved effective model of Quantum Chromodynamics (QCD) at low energies, to investigate the exis…
Thermal evolution of hybrid stars within the framework of a nonlocal Nambu--Jona-Lasinio model
S. M. de Carvalho, R. Negreiros, M. Orsaria +3
We study the thermal evolution of neutron stars containing deconfined quark matter in their core. Such objects are generally referred to as quark-hybrid stars. The confined hadroni…
Properties of High-Density Matter in Neutron Stars
Fridolin Weber, Gustavo A. Contrera, Milva G. Orsaria +2
This short review aims at giving a brief overview of the various states of matter that have been suggested to exist in the ultra-dense centers of neutron stars. Particular emphasis…
Hadron-Quark Phase Transition in Quark-Hybrid Stars
Gustavo A. Contrera, William Spinella, Milva Orsaria +1
The recent discovery of the two-solar mass neutron stars and allows to consider the possible existence…
Testing the spin-cutoff parameterization with shell-model calculations
William M. Spinella, Calvin W. Johnson
The nuclear level density, an important input to Hauser-Feshbach calculations, depends not only on excitation energy but also on angular momentum J. The J-dependence of the level d…
