Radial oscillations of strange quark stars admixed with condensed dark matter
Grigoris Panotopoulos, Ilidio Lopes
We compute the 20 lowest frequency radial oscillation modes of strange stars admixed with condensed dark matter. We assume a self-interacting bosonic dark matter, and we model dark…
The dark matter effect on realistic equation of state in neutron stars
Grigoris Panotopoulos, Ilidio Lopes
In this work we apply relativistic mean-field theory in neutron stars assuming that fermionic dark matter is trapped inside the star and interacts directly with neutrons by exchang…
Constraining the parameter space of branon dark matter using white dwarf stars
Grigoris Panotopoulos, Ilidio Lopes
In the present work we study the branon dark matter particles impact on compact objects, and we provide the first constraints of the parameter space using white dwarf stars. The br…
Neutron stars: A novel equation of state with induced surface tension
Violetta V. Sagun, Ilidio Lopes
A novel equation of state with the surface tension induced by particles' interactions was generalized to describe the properties of the neutron stars (NSs). In this equation the in…
Gravitational effects of condensed dark matter on strange stars
Grigoris Panotopoulos, Ilidio Lopes
In the present work we study the gravitational effects of condensed dark matter on strange stars. We consider self-interacting dark matter particles with properties consistent with…
Constraining the scalar singlet and inert dark matter models using neutron stars
Grigoris Panotopoulos, Ilidio Lopes
In the present work we study the scalar singlet as well as the Two-Higgs Doublet model inert dark matter particles impact on compact objects, and we provide the first constraints o…
