Compactness in the Thermal Evolution of Twin Stars
F. Lyra, L. Moreira, R. Negreiros +2
In this work, we study for the first time the thermal evolution of twin star pairs, i.e., stars that present the same mass but different radius and compactness. We collect availabl…
GW190814 as a massive rapidly-rotating neutron star with exotic degrees of freedom
V. Dexheimer, R. O. Gomes, T. Klähn +2
In the context of the massive secondary object recently observed in the compact-star merger GW190814, we investigate the possibility of producing massive neutron stars from a few d…
The possibility of twin star solutions in a model based on lattice QCD thermodynamics
P. Jakobus, A. Motornenko, R. O. Gomes +2
The properties of compact stars and in particular the existence of twin star solutions are investigated within an effective model that is constrained by lattice QCD thermodynamics.…
Limiting magnetic field for minimal deformation of a magnetised neutron star
R. O. Gomes, Helena Pais, V. Dexheimer +2
In this work we study the structure of neutron stars under the effect of a poloidal magnetic field and determine the limiting highest magnetic field intensity which still allows a…
Phase Transitions in Neutron Stars
V. Dexheimer, L. T. T. Soethe, J. Roark +3
In this paper we review the most common descriptions for the first order phase transition to deconfined quark matter in the core of neutron stars. We also present a new description…
Can magnetic fields stabilize or destabilize twin stars?
R. O. Gomes, V. Dexheimer, S. Han +1
Sharp phase transitions described by stiff equations of state allow for the existence of a third family of stable compact stars (besides white dwarfs and neutron stars), twin stars…
What do we learn about vector interactions from GW170817?
Veronica Dexheimer, Rosana de Oliveira Gomes, Stefan Schramm +1
We analyze the role played by vector-isovector meson interaction in dense matter present in the interior of neutron stars in the light of new measurements made during the double ne…
Constraining strangeness in dense matter with GW170817
R. O. Gomes, Prasanta Char, S. Schramm
Particles with strangeness content are predicted to populate dense matter, modifying the equation of state of matter inside neutron stars as well as their structure and evolution.…
Modeling magnetic neutron stars: a short overview
R. O. Gomes, S. Schramm, V. Dexheimer
Neutron stars are the endpoint of the life of intermediate mass stars and posses in their cores matter in the most extreme conditions in the universe. Besides their extremes of tem…
Many-body forces in magnetic neutron stars
R. O. Gomes, B. Franzon, V. Dexheimer +1
In this work, we study in detail the effects of many-body forces on the equation of state and the structure of magnetic neutron stars. The stellar matter is described within a rela…

V. Dexheimer, B. Franzon, R. O. Gomes +3
In this work, we expand on a previously reported realistic calculation of the magnetic field profile for the equation of state inside strongly magnetized neutron stars. In addition…

R. O. Gomes, B. Franzon, V. Dexheimer +2
In this work, we study the effects of different magnetic field configurations in neutron stars described by a many-body forces formalism (MBF model). The MBF model is a relativisti…
