Asteroseismic study investigates differential core rotation in Gamma Doradus stars, highlighting detectability through inertial dips.
Key Points
The aim is to analyze differential rotation between the convective core and near-core region of gamma Doradus stars using the properties of inertial dips.
Studied coupling between gravito-inertial modes and pure inertial modes in the convective core.
Employed numerical solutions and analytical derivations of Lorentzian dip properties.
Used Kepler data to infer parameters for detectable differential rotation.
Increasing convective core rotation shifts the observed dip to lower periods.
The dip becomes deeper and thinner with increased convective core rotation.
Signatures of differential rotation are detectable in current Kepler data.
