Effect of Torsion on Neutron Star Structure in Einstein-Cartan Gravity
Cédric Jockel, Leon Menger
Einstein-Cartan gravity is a close historical sibling of general relativity that allows for spacetime torsion. As a result, angular momentum couples to spacetime geometry in a simi…
A Theoretical Framework for Self-Gravitating k-Form Boson Stars with Internal Symmetries
Jakob Hoffmann, Cédric Jockel
Current boson star models are largely restricted to global symmetries and lower spin fields. In this work, we generalize these systems of self-gravitating bosonic fields to allow f…
Fermion Proca Stars: Vector Dark Matter Admixed Neutron Stars
Cédric Jockel, Laura Sagunski
Dark matter could accumulate around neutron stars in sufficient amounts to affect their global properties. In this work, we study the effect of a specific model for dark matter --…
Scalar- and Vector Dark Matter Admixed Neutron Stars
Cédric Jockel
It is believed that dark matter (DM) could accumulate inside neutron stars and significantly change their masses, radii and tidal properties. We study what effect bosonic dark matt…
Tidal Deformability of Fermion-Boson Stars: Neutron Stars Admixed with Ultra-Light Dark Matter
Robin Fynn Diedrichs, Niklas Becker, Cédric Jockel +3
In this work we investigate the tidal deformability of a neutron star admixed with dark matter, modeled as a massive, self-interacting, complex scalar field. We derive the equation…
