Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO

Avishek Basu, Vanessa Graber, Marcus E. Lower +19

Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…

Magnetized neutron stars: perturbative versus fully-numerical approaches

Debarati Chatterjee, Daw Guttmann, Jérôme Novak +2

(1) Background: for the study of highly magnetized neutron stars observed as magnetars, and to quantify the effect of this intense magnetic field onto the star's structure and shap…

Rapidly rotating hot nuclear and hypernuclear compact stars: integral parameters and universal relations

Stefanos Tsiopelas, Armen Sedrakian, Micaela Oertel

In this work, we investigate hot, isentropic compact stars in the limiting cases of static and maximally rotating configurations, focusing on how variations in the symmetry energy…

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…

Numerical simulations of oscillating and differentially rotating neutron stars

Santiago Jaraba, Jérôme Novak, Micaela Oertel

The remnants of binary neutron star mergers are expected to be massive, rapidly rotating stars whose oscillations produce gravitational waves in the kilohertz band. The degree of d…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…
