- Abstract
More than 30 years ago the first pulsating pre-main sequence (PMS) stars have been discov- ered. Since then, pulsations in 18 Herbig Ae stars and 18 members of young open clusters were detected and detailed asteroseismic investigations were conducted for some of them. We describe our latest results in this field. Using ground-based observations of NGC 6530 278, it was possible for the first time to show that the star¿s observed frequency spectrum can only be explained by a PMS model. Observations obtained with the MOST space telescope allowed to study the pulsations of the enigmatic Herbig Ae star HD 142666, which is also surrounded by a dense circumstellar disk. In addition, 4 new pulsating PMS stars were discovered in the young open cluster NGC 2264 based on time-series photometry with the MOST satellite.
