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 parametrisation 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…
Constraining equation of state groups from -mode asteroseismology
Hao-Jui Kuan, Christian J. Krüger, Arthur G. Suvorov +1
Buoyancy-restored modes inside neutron stars depend sensitively on both the microphysical (e.g., composition and entropy gradients) and macrophysical (e.g., stellar mass and radius…
Oscillations and instabilities of fast and differentially rotating relativistic stars
Christian Krüger, Erich Gaertig, Kostas D. Kokkotas
We study non-axisymmetric oscillations of rapidly and differentially rotating relativistic stars in the Cowling approximation. Our equilibrium models are sequences of relativistic…
