Surface rotation and photometric activity for Kepler targets. II. G and F main-sequence stars, and cool subgiant stars

A. R. G. Santos, S. N. Breton, S. Mathur +1

Dark magnetic spots crossing the stellar disc lead to quasi-periodic brightness variations, which allow us to constrain stellar surface rotation and photometric activity. The curre…

Asteroseismology of iota Draconis and Discovery of an Additional Long-Period Companion

Michelle L. Hill, Stephen R. Kane, Tiago L. Campante +25

Giant stars as known exoplanet hosts are relatively rare due to the potential challenges in acquiring precision radial velocities and the small predicted transit depths. However, t…

A calibration of the Rossby number from asteroseismology

E. Corsaro, A. Bonanno, S. Mathur +4

Stellar activity and rotation are tightly related in a dynamo process. Our understanding of this mechanism is mainly limited by our capability of inferring the properties of stella…

ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods

Sylvain N. Breton, Angela R. G. Santos, Lisa Bugnet +3

In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. An efficient tool to automatically determine reliable rotation pe…

Determining surface rotation periods of solar-like stars observed by the Kepler mission using machine learning techniques

S. N. Breton, L. Bugnet, A. R. G. Santos +4

For a solar-like star, the surface rotation evolves with time, allowing in principle to estimate the age of a star from its surface rotation period. Here we are interested in measu…

Tidal heating in multilayer planets: Application to the TRAPPIST-1 system

Sylvain Breton, Emeline Bolmont, Gabriel Tobie +1

TRAPPIST-1 (Gillon et al. 2017) is an extremely compact planetary system: seven earth-sized planets orbit at distances lower than 0.07 AU around one of the smallest M-dwarf known i…
