Rapid neutron star cooling triggered by dark matter
Afonso Ávila, Edoardo Giangrandi, Violetta Sagun +2
We study the effect of asymmetric fermionic dark matter (DM) on the thermal evolution of neutron stars (NSs). No interaction between DM and baryonic matter is assumed, except the g…
What is the nature of the HESS J1731-347 compact object?
Violetta Sagun, Edoardo Giangrandi, Tim Dietrich +3
Once further confirmed in future analyses, the radius and mass measurement of HESS J1731-347 with and will be amo…
How does dark matter affect compact star properties and high density constraints of strongly interacting matter
Violetta Sagun, Edoardo Giangrandi, Oleksii Ivanytskyi +2
We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution i…
The effects of self-interacting bosonic dark matter on neutron star properties
Edoardo Giangrandi, Violetta Sagun, Oleksii Ivanytskyi +2
We propose a model of asymmetric bosonic dark matter (DM) with self-repulsion mediated by the vector field coupled to the complex scalar particles. By adopting the two-fluid formal…
Tidal Deformability as a Probe of Dark Matter in Neutron Stars
Davood Rafiei Karkevandi, Soroush Shakeri, Violetta Sagun +1
The concept of boson stars (BSs) was first introduced by Kaup and Ruffini-Bonazzola in the 1960s. Following this idea, we investigate an effect of self-interacting asymmetric boson…
Bosonic Dark Matter in Neutron Stars and its Effect on Gravitational Wave Signal
Davood Rafiei Karkevandi, Soroush Shakeri, Violetta Sagun +1
We study an impact of self-interacting bosonic dark matter (DM) on various observable properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses fro…
