Relevant issues in the study of Pre-Main Sequence Delta Scuti stars

Abstract

We will review the theoretical and observational developments in the study of Pre-Main Sequence (PMS) δ Scuti stars and point out some current open problems. In particular, we stress the strong need for multi-site and/or space-based observations and for nonradial pulsation modelling. The most recent observations of the best studied object, V351 Ori, and the preliminary results of the application of a nonradial code to PMS δ Scuti stars will also be discussed.
