Spontaneous scalarization in proto-neutron stars [PDF]
European Physical Journal C: Particles and Fields, 2023 Proto-neutron stars are born when a highly evolved and massive star collapses under gravity. In this paper, we investigate the spontaneous scalarization in proto-neutron stars.

Hyperons in Neutron Stars [PDF]
Universe, 2021 I review the issues related to the appearance of hyperons in neutron star matter, focusing in particular on the problem of the maximum mass supported by hyperonic equations of state. I discuss the general mechanism that leads to the formation of hyperons

Insights on Skyrme parameters from GW170817
Physics Letters B, 2019 The binary neutron-star merger event, GW170817, has cast a new light on nuclear physics research. Using a neutron-star model that includes a crust equation of state (EoS), we calculate the properties of a 1.4 solar-mass neutron star.

Cooling of neutron stars with quark-hadron continuity [PDF]
EPJ Web of Conferences, 2022 Neutron stars are high-density objects formed by the gravitational collapse of massive stars, and the whole star can be likened to a giant nucleus. The interior of a neutron star is considered to contain exotic particles and states which do not appear in

Universe, 2022 Neutron star is an important object for us to verify the equation of state of hadronic matter. For a specific choice of equations of state, mass and radius of a neutron star are determined, for which there are constraints from observations.

Journal of High Energy Physics, 2022 We investigate the form of the radiation emitted by an axion star-neutron star binary using a f(r) = sech(r/R) profile for the axion star. Our analysis takes into account the co-rotating plasma of the neutron star.

The origin of the first neutron star – neutron star merger [PDF]
Astronomy & Astrophysics, 2018 The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This merger was detected in an old elliptical galaxy with no recent star formation. We perform a suite of numerical calculations to understand the formation mechanism of this merger.

Universe, 2021 A neutron star was first detected as a pulsar in 1967. It is one of the most mysterious compact objects in the universe, with a radius of the order of 10 km and masses that can reach two solar masses. In fact, neutron stars are star remnants, a kind of stellar zombie (they die, but do not disappear).

Inferring the dense nuclear matter equation of state with neutron star tides [PDF]
EPJ Web of Conferences, 2022 During the late stages of a neutron star binary inspiral finite-size effects come into play, with the tidal deformability of the supranuclear density matter leaving an imprint on the gravitational-wave signal.
