Scientific paper

Results of a radio survey of weak-lined T Tauri (variably classified as either post T Tauri or naked T Tauri) stars at 5 GHz are reported. Thirty-two targets, chosen on the basis of known high-activity levels or youth indications, were observed, and 15, including eight previously unknown radio sources, were detected. It is suggested that most weak-lined T Tauris with high activity levels, e.g., as indicated by a high X-ray flux, are likely to be detectable radio sources at some time, but the radio emission goes through high and low phases. For the subsample of 14 stars observed in Taurus-Auriga which were thoroughly studied at IR, optical, and X-ray wavelengths, a clear association is found between radio activity and youth.
