   ASCA observations of star formation regions in dark (molecular)
   clouds have demonstrated the power and utility of X-ray spectroscopy
   of embedded T Tauri stars (TTS). A major difficulty with analysis of
   the extant data, however, is the large hydrogen column through dark
   clouds and the likely presence of multiple sources within the ASCA
   point spread function. Also, it is increasingly apparent that a
   significant number of TTS are located far from cloud cores. We
   propose to obtain ASCA spectra of nearby TTS that are several degrees
   from the nearest dark clouds and other young stars. The proposed
   observations will yield the first unobscured X-ray spectra of
   individual TTS, and in so doing, will shed light on the origin and
   nature of isolated TTS.
