Neutrinos and Asteroseismology of Stars over the Helium Flash
Diogo Capelo, Ilídio Lopes
The helium flash, occurring in stars of 0.6-2.0 M at the end of the red giant branch, is not observable via optical means due to the energy of the process being used to lif…
Asteroseismology: Looking for axions in the red supergiant star Alpha Ori
Clara Severino, Ilídio Lopes
In this work, for the first time, we use seismic data as well as surface abundances to model the supergiant -Ori, with the goal of setting an upper bound on the axion-photon cou…
On asymmetric dark matter constraints from the asteroseismology of a subgiant star
João Rato, José Lopes, Ilídio Lopes
The asteroseismic modelling of solar-like stars has proved to be valuable in constraining dark matter. In this work we study for the first time the influence of asymmetric dark mat…
Asteroseismology of low-mass stars: the balance between partial ionisation and Coulomb interactions
Ana Brito, Ilídio Lopes
All cool stars with outer convective zones have the potential to exhibit stochastically excited stellar oscillations. In this work, we explore the outer layers of stars less massiv…
Dark matter capture and annihilation in stars: Impact on the red giant branch tip
José Lopes, Ilídio Lopes
Context: While stars have often been used as laboratories to study dark matter (DM), red giant branch (RGB) stars and all the rich phenomenology they encompass have frequently been…
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…
