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.
