Abstract:
Rotation periods for these stars indicate they are not, as a group, fast-rotating stars. The non-detection in radio supports the findings of other radio surveys of inhomogeneous samples of young stars, where radio emission is fairly common (10-30%) among very young T Tauri stars across all late spectral types, but confined to rapidly-rotating F-G-K stars amongst older Zero-Age Main Sequence stars. Rotation, moreso than youth, appears to be the key to radio-emission in young stars.
