Nuclear-physics-guided Gaussian Processes
Javier Rozalén Sarmiento, Hristijan Kochankovski, Arnau Rios +1
Gaussian Process Regression is a powerful nonparametric Bayesian method that provides both predictions and principled uncertainty estimates in closed form. The majority of past app…
Hyperonic degrees of freedom in binary neutron star mergers
Laura Tolos, Hristijan Kochankovski, Angels Ramos +3
We analyze the influence of hyperons in binary neutron star mergers considering several different equations of state that include hyperons. By running a large set of simulations, w…
Moat hyperons in cold neutron stars
Hristijan Kochankovski, Angels Ramos, Laura Tolos
We investigate the hyperonic equation of state within the non-linear derivative model that incorporates a momentum dependence on the interactions, with a special emphasis on proper…
Stellar properties indicating the presence of hyperons in neutron stars
Andreas Bauswein, Aristeidis Nikolaidis, Georgios Lioutas +7
We describe distinctive stellar features indicating the presence of hyperons in neutron stars as compared to purely nucleonic systems. A strongly negative curvature of the mass-rad…
The impact of hyperons on neutron star mergers: gravitational waves, mass ejection and black hole formation
Hristijan Kochankovski, Georgios Lioutas, Sebastian Blacker +3
We study the influence of hyperons in binary neutron star (NS) mergers considering a total of 14 temperature dependent equations of state (EoSs) models which include hyperonic degr…
Hyperons in neutron star mergers
Hristijan Kochankovski, Angels Ramos, Laura Tolos +2
We discuss the effects induced by the potential presence of hyperons in hot and ultra-dense matter within the context of neutron star mergers. Specifically, we address their effect…
Hyperons during proto-neutron star deleptonization and the emission of dark flavoured particles
Tobias Fischer, Jorge Martin Camalich, Hristijan Kochankovski +1
Complementary to high-energy experimental efforts, indirect astrophysical searches of particles beyond the standard model have long been pursued. The present article follows the la…
Hyperonic uncertainties in neutron stars, mergers and supernovae
Hristijan Kochankovski, Angels Ramos, Laura Tolos
In this work we delve into the temperature-dependent Equation of State (EoS) of baryonic matter within the framework of the FSU2H hadronic model, which comprehensively incorpor…
Thermal behavior as indicator for hyperons in binary neutron star merger remnants
Sebastian Blacker, Hristijan Kochankovski, Andreas Bauswein +2
We provide the first comprehensive study of hyperons in neutron star mergers and quantify their specific impact. We discuss the thermal behavior of hyperonic equations of state~(Eo…
Finite-temperature equation of state with hyperons
Hristijan Kochankovski, Angels Ramos, Laura Tolos
We present the novel finite-temperature FSU2H equation-of-state model that covers a wide range of temperatures and lepton fractions for the conditions in proto-neutron stars, n…
Hyperonic equation of state at finite temperature for neutron stars
Hristijan Kochankovski, Angels Ramos, Laura Tolos
We review the composition and the equation of state of the hyperonic core of neutron stars at finite temperature within a relativistic mean-field approach. We make use of the new F…
Equation of state for hot hyperonic neutron star matter
Hristijan Kochankovski, Angels Ramos, Laura Tolos
The FSU2H equation-of-state model, originally developed to describe cold neutron star matter with hyperonic cores, is extended to finite temperature. Results are presented for a wi…
