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…
