   Recent ROSAT and ASCA observations of nearby molecular clouds have
   shown that X-ray emission starts very early in stellar evolution.
   Whereas X-ray emission from T Tauri stars is now fairly well
   understood in terms of magnetic activity, the high-energy (up to 10
   keV) radiation from protostars is not understood. The X-ray emission
   from young stars may have profound implications on star formation,
   envelope collapse, and outflow acceleration at early stages. We want
   to confirm the detection of protostars, which is still tentative
   because of extinction/confusion problems. We take advantage of the
   ASCA's unique capability to detect higher-energy X-rays (which suffer
   less extinction), but selecting isolated protostars (to avoid
   confusion with closeby young stars, as has been the case until now).
