Combining simulation-based inference and universal relations for precise and accurate neutron star science
Christian J. Krüger, Sebastian H. Völkel
In this work, we propose a novel approach for identifying, constructing, and validating precise and accurate universal relations for neutron star bulk quantities. A central element…

Universal relations for fast rotating neutron stars without equation of state bias
Christian J. Krüger, Mariachiara Celato
We provide a summary of several parametrisations for the nuclear equation of state that have been proposed over the past decades and list viable ranges for their parameters. Based…

Neutron stars in Gauss-Bonnet gravity -- nonlinear scalarization and gravitational phase transitions
Daniela D. Doneva, Christian J. Krüger, Kalin V. Staykov +1
It was recently discovered that scalarized neutron stars in scalar-tensor theories can undergo a gravitational phase transition to a non-scalarized (GR) state. Surprisingly, even t…
