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…
Slowly rotating dark energy stars
Grigoris Panotopoulos, Ángel Rincón, Ilídio Lopes
We study isotropic and slowly-rotating stars made of dark energy adopting the extended Chaplygin equation-of-state. We compute the moment of inertia as a function of the mass of th…
Interacting dark sector: Lagrangian formulation based on two canonical scalar fields
Grigoris Panotopoulos, Ilídio Lopes
We study in some detail an interacting cosmological model based on two canonical scalar fields starting from a Lagrangian description. Contrary to other more phenomenological appro…
Accretion of matter and spectra of Binary X-ray sources in Massive Gravity
Grigoris Panotopoulos, Angel Rincon, Ilídio Lopes
We study low-mass binary X-ray sources involving stellar mass black holes within massive gravity. Regarding the accretion disk, we adopt the standard model for an optically thick,…
ISCOs and OSCOs in the presence of a positive cosmological constant in massive gravity
Angel Rincon, Grigoris Panotopoulos, Ilidio Lopes +1
We study the impact of a non-vanishing (positive) cosmological constant on the innermost and outermost stable circular orbits (ISCOs and OSCOs, respectively) within massive gravity…
