Recent results on Pre-main sequence delta Scuti stars

Abstract

Intermediate mass Pre-main sequence stars (1.5 $M_{\odot}< M < 5M_{\odot}$) cross the instability strip on their way to the main sequence. They are therefore expected to be pulsating in a similar way as the $\delta$ Scuti stars. In this contribution we present the status of the observational studies of pulsations in these stars with special emphasis on recent results from our group. The prospects for future investigations of these objects from the ground and from space are discussed.
