Hybrid pulsators among A/F-type stars

TL;DR

This review discusses hybrid pulsators among A/F-type main sequence stars, highlighting recent discoveries of stars exhibiting multiple pulsation types thanks to space missions, and explores their astrophysical implications.

Contribution

It provides a comprehensive overview of hybrid pulsators, integrating recent asteroseismic findings and discussing their significance for stellar physics.

Findings

Detection of Gamma Doradus variability in a rapidly oscillating Ap star

Discovery of solar-like oscillations in a Delta Scuti star

Enhanced understanding of pulsational driving mechanisms

Abstract

This article reviews the present knowledge on oscillating main sequence A/F stars that belong to more than one class of pulsator. Due to recent results of asteroseismic space missions, we now know of many Delta Scuti/Gamma Doradus stars. However, Gamma Doradus variability was also detected in a rapidly oscillating Ap star, and solar-like oscillations were discovered in a Delta Scuti star. The astrophysical information that can be gained from these pulsators is discussed, and confronted with what is believed to be known about pulsational driving.
