Revisiting the Impact of Stellar Magnetic Activity on the Detectability of Solar-Like Oscillations by Kepler
Over 2,000 stars were observed for 1 month with a high enough cadence in order to look for
acoustic modes during the survey phase of the Kepler mission. Solar-like oscillations have …

Stochastic excitation of waves in magnetic stars-I. Scaling laws for the mode amplitudes
Context. Stellar oscillations are key to unravelling stellar properties, such as their mass,
radius, and age. This in turn enables us to date and characterize their exoplanetary systems …

Asteroseismic constraints on active latitudes of solar-type stars: HD 173701 has active bands at higher latitudes than the Sun
We present a new method for determining the location of active bands of latitude on solar-
type stars, which uses stellar-cycle-induced frequency shifts of detectable solar-like …

Relations between global seismic parameters and activity cycles of the Sun
It is suggested that the dependency of the global asteroseismic parameters on stellar
properties such as magnetic activity is carefully calibrated with a homogenous data sample …
