Hints of enhanced magnetic activity after the intermediate rotation period gap as traced by the chromospheric Ca ii infrared triplet

Diego Godoy-Rivera, Savita Mathur, Tyler Richey-Yowell +5

For low-mass stars (M < 1.4 Msun), the connection between stellar rotation and magnetic activity governs stellar spin-down, shapes the environments of their exoplanets, and provide…

Influence of the magnetic activity cycle on mean density and acoustic radius inversions

Jérôme Bétrisey, Daniel R. Reese, Sylvain N. Breton +4

Asteroseismic modelling is crucial for upcoming missions like PLATO, CubeSpec, and Roman. Despite significant progress, discrepancies between observations and theoretical predictio…

Signature of spin-down stalling in stellar magnetic activity. The case of the open cluster NGC 6811

Ângela R. G. Santos, Diego Godoy-Rivera, Savita Mathur +3

Stellar rotation and magnetic activity have a complex evolution that reveals multiple regimes. One of the related transitions that is seen in the rotation distribution for main-seq…

Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets

Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16

There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…

The impact of rotation on the stochastic excitation of stellar acoustic modes in solar-like pulsators

Leïla Bessila, Adrien Deckx van Ruys, Valentin Buriasco +4

Recent observational results from asteroseismic studies show that an important fraction of solar-like stars do not present detectable stochastically excited acoustic oscillations.…

Impact of uniform rotation on the stochastic excitation of acoustic modes in solar-like oscillators

Leïla Bessila, Adrien Deckx Van Ruys, Valentin Buriasco +4

We evaluate the impact of the rotation on the stochastic excitation of acoustic (p) modes in solar-like pulsators. First, we derive the forced wave equation taking rotation into ac…
