From core to envelope: revealing the deep dynamics of stars with two convective zones
Sylvain N. Breton, Allan Sacha Brun, Rafael A. GarcÃa
On the Hertzsprung-Russell diagram, F-type solar pulsators connect the Sun to intermediate mass stars located on the instability strip. With respect to lower mass stars, they are s…
Hidden worlds: a non-transiting candidate planet in the Neptunian desert around the solar-type pulsator KIC 9139163
Sylvain N. Breton, Achrène Dyrek, Carlos Allende Prieto +16
Close-in substellar companions experience strong tidal and magnetic interactions with their host stars and are therefore subject to fast orbital evolution. The solar-type pulsator…
Core-envelope coupling of gravito-inertial waves in pre-main-sequence solar-type stars
Sylvain N. Breton, Camilla Pezzotti, Stéphane Mathis +5
After the recent detection of solar equatorial Rossby waves, a renewed interest has been brought to the study of gravito-inertial waves propagating in the convective envelope of so…
Is convective turbulence the only exciting mechanism of global p modes in the Sun?
E. Panetier, R. A. GarcÃa, S. N. Breton +2
In solar-like oscillators, acoustic waves are excited by turbulent motion in the convective envelope and propagate inward, generating a variety of standing pressure modes. When com…
Non-transiting exoplanets as a means of understanding star-planet interactions in close-in systems
C. Gourvès, S. N. Breton, A. Dyrek +5
Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic interactions b…
