Pre-main sequence (PMS) stars lie between the birthline and the zero-age main sequence (ZAMS) in the Hertzsprung-Russell (HR) diagram. They show photometric and spectroscopic variability on time scales of minutes to years, indicating that photospheric activity begins in the earliest phases of stellar evolution. The fact that they move across the instability region during their evolution to the main sequence suggests that at least part of their activity is due to stellar pulsation.
The total number of only 10 known Scuti like pulsators is absolutely insufficient for the observational definition of the PMS instability strip.
Young open clusters where all members with spectral types later than A0 lie above the ZAMS are ideal objects for the search for pulsation in PMS stars.
We will present recent results on the search for pulsation in PMS stars in the young open cluster NGC 6383 for which time series photometry was obtained in August 2001 at CTIO.
