The impact of composition choices on solar evolution: age, helio- and asteroseismology, and neutrinos
Diogo Capelo, Ilídio Lopes
The Sun is the most studied and well-known star, and as such, solar fundamental parameters are often used to bridge gaps in the knowledge of other stars, when these are required fo…
Core magnetic field imprint in the non-radial oscillations of red giant stars
Pedro Gomes, Ilídio Lopes
Magnetic fields in red giant stars remain a poorly understood topic, particularly in what concerns their intensity in regions far below the surface. In this work, we propose that g…
The partial ionisation zone of heavy elements in F-stars: a study on how it correlates with rotation
Ana Brito, Ilídio Lopes
We study the relation between the internal structures of 10 benchmark main-sequence F-stars and their rotational properties. Stellar rotation of main-sequence F-type stars can be c…
From cool to hot F-stars: the influence of two ionization regions in the acoustic oscillations
Ana Brito, Ilídio Lopes
The high-precision data available from the Kepler satellite allows us to venture in the study of the complex outer convective envelopes of solar-type stars. We use a seismic diagno…
Quadrupole stellar oscillations: The impact of gravitational waves from the Galactic Center
Ilídio Lopes
Acoustic quadrupole modes of sunlike stars vibrate when perturbed by a passing gravitational wave generated somewhere in the Universe. Here, we compute the imprint of the gravitati…
A Theoretical Study of the Outer Layers of Eight Kepler F-stars: The Relevance of Ionization Processes
Ana Brito, Ilídio Lopes
We have analyzed the theoretical model envelopes of eight Kepler F-stars by computing the phase shift of the acoustic waves, , and its related function, . The latter is…
