Constraining dark photon properties with Asteroseismology
Adrián Ayala, Ilidio Lopes, Antonio García Hernández +2
Dark photons are particles invoked in some extensions of the Standard Model which could account for at least part of the dark matter content of the Universe. It has been proposed t…
Neutron stars: new constraints on asymmetric dark matter
O. Ivanytskyi, V. Sagun, I. Lopes
We study an impact of asymmetric dark matter on properties of the neutron stars and their ability to reach the two solar masses limit, which allows us to present a new range of mas…
Obtaining Precision Constraints on Modified Gravity with Helioseismology
Ippocratis D. Saltas, Ilídio Lopes
We propose helioseismology as a new, precision probe of fifth forces at astrophysical scales, and apply it on the most general scalar-tensor theories for dark energy, known as Dege…
Asymmetric Dark Matter Imprint on Low-mass Main-sequence Stars in the Milky Way Nuclear Star Cluster
José Lopes, Ilídio Lopes
In this work, we study the impact of asymmetric dark matter (ADM) on low-mass main-sequence stars in the Milky Way's nuclear star cluster, where the dark matter (DM) density is exp…
Anisotropic strange quark stars with a non-linear equation-of-state
Ilídio Lopes, Grigoris Panotopoulos, Ángel Rincón
We obtain an exact analytical solution to Einstein's field equations assuming a non-linear equation-of-state and a particular mass function. Our solution describes the interior of…
Radial oscillations of boson stars made of ultralight repulsive dark matter
Ilídio Lopes, Grigoris Panotopoulos
We compute the lowest frequency radial oscillation modes of boson stars. It is assumed that the object is made of pseudo-Goldstone bosons subjected to a scalar potential that leads…
