Ultra-compact twin stars with hybrid equations of state from bosonic dark matter
Ishfaq Ahmad Rather, Sarah Louisa Pitz, Jürgen Schaffner-Bielich
The properties of compact stars with a strong first-order phase transition to quark matter and with an additional fluid of self-interacting bosonic dark matter (DM) are studied. We…

Generating ultra-compact neutron stars with bosonic dark matter
Sarah Louisa Pitz, Jürgen Schaffner-Bielich
In this work we investigate the properties of neutron stars admixed with selfinteracting scalar bosonic dark matter. The dark matter interaction is described by a generalized …

Generating ultra compact boson stars with modified scalar potentials
Sarah Louisa Pitz, Jürgen Schaffner-Bielich
The properties of selfinteracting boson stars with different scalar potentials going beyond the commonly used ansatz are studied. The scalar potential is extended to differen…
