  We present a 8.4 GHz VLA survey of 50 optical counterparts to 46 ROSAT
All-Sky survey (RASS) X-ray sources south of the Taurus-Auriga star-forming
region. This survey detected 3 sources with a sensitivity limit of ~ 0.12 mJy.
Merging our sample with other radio observations of sources in and around
Taurus-Auriga, we find scarce radio emission among RASS sources south of the
Taurus-Auriga molecular clouds. Our data support the evidence that these
sources are older than weak-lined T Tauri stars, most of them probably being
close to the ZAMS.
