Abstract

Star formation efficiency in translucent molecular clouds has long been an unresolved and key issue in the field of low-mass star formation. In this paper, we report on the results of our survey for low-mass star formation in high-Galactic latitude molecular clouds, especially those of the translucent category, based on the ROSAT All-Sky Survey. Nine new weak-line T Tauri star candidates have been discovered at high-Galactic latitudes, among which, 6 are seen against - thus possibly associated with - the translucent molecular clouds, MBM 16, MBM 19 and MBM 55. Further study on the Li-rich X-ray active sources is necessary to shed more light on star formation in translucent molecular clouds.
