Forecasting Seismic Signatures of Stellar Magnetic Activity

TL;DR

This paper predicts how stellar magnetic activity influences seismic oscillation frequencies by scaling solar relations, suggesting these effects are measurable in upcoming observational data.

Contribution

It introduces a method to forecast stellar seismic signatures of magnetic activity by scaling from solar data, filling a gap in stellar activity studies.

Findings

Predicted activity-induced frequency changes in stars

Seismic signatures should be detectable within a few years

Provides a framework for interpreting stellar magnetic activity data

Abstract

For the Sun, a tight correlation between various activity measures and oscillation frequencies is well documented. For other stars, we have abundant data on magnetic activity and its changes but not yet on its seismic signature. A prediction of the activity induced frequency changes in stars based on scaling the solar relations is presented. This seismic signature of the activity should be measurable in the data expected within few years.
