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…
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…
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 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…
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…
