Abstract
We present first results of Hipparcos observations of nearby low-mass pre-m ain-sequence (PMS) stars (T Tauri and Herbig Ae/Be stars). The data obtaine d by Hipparcos allow us to derive weighted mean parallaxes for three major nearby star-forming regions (SFRs), Lupus, Chamaeleon I and Taurus-Auriga. Furthermore, results on the isolated objects AB Dor and TW Hya are presente d. Finally, we discuss the evolutionary status of Herbig Ae/Be (HAEBE) star s on the basis of Hipparcos results.
