In-flight calibration of RADEM, the JUICE mission radiation monitor
Marco Pinto, Francisca Santos, António Gomes +7
The RADiation-hard Electron Monitor (RADEM) aboard the Jupiter Icy Moons Explorer (JUICE), launched on 14 April 2023, measures high-energy protons and electrons during the cruise p…
A study of the electrostatic properties of the interiors of low-mass stars: Possible implications for the observed rotational properties
Ana Brito, Ilídio Lopes
In the partially ionized material of stellar interiors, the strongest forces acting on electrons and ions are the Coulomb interactions between charges. The dynamics of the plasma a…
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…
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…
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…
