Radio continuum emission from premain sequence stars and associated structures

VLA 6 cm (4860 MHz with 100 MHz total bandwidth) C-array observations of regions of recent star formation containing premain sequence (PMS) stars, Herbig-Haro objects, and stellar jets, are presented. Three PMS stars, HL Tau, XZ Tau and FS Tau, were definitely (6-sigma) detected and FS Tau B is possibly (5-sigma) detected. The mass loss rates implied for spherically-symmetric stellar winds with outflow velocities of 200 km/s are in the range 1-2 x 10 to the -8th solar masses/yr. HL Tau shows extended structure including a 3-sigma detection of emission possibly associated with the jet from this star. No Herbig-Haro objects were detected at a typical 3-sigma rms level of 0.12 mJy/beam.
