Part of the Lecture Notes in Physics book series (LNP, volume 291)


The Naked T Tauri stars (NTTS) are a population of low mass, pre-main sequence stars which lack the continuum excesses and strong emission lines of the classical T Tauri stars (CTTS). Some 150 such stars are now known in and near regions of star formation in Tau-Aur, Ori, Sco-Oph, and CrA. I briefly review the properties of the NTTS. I then summarize recent results of searches for NTTS in the II Sco and Ori OBIc OB associations. These data are used to investigate the stellar populations and mass functions in regions of star formation.
