Asteroseismic constraints on active latitudes of solar-type stars: HD 173701 has active bands at higher latitudes than the Sun

AEL Thomas, WJ Chaplin, GR Davies… - Monthly Notices of …, 2019 - academic.oup.com
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

KB Kim, HY Chang - New Astronomy, 2022 - Elsevier
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 …
