Abstract
We have detected X-ray emission (1 keV) from young intermediate-mass s tars (Herbig Ae/Be stars). Since these stars are not supposed to produ ce intrinsic X-ray emission (no convection, no coronae), we believe th at our results suggest that the X-ray emission actually traces the sho ck interaction of the Ae/Be star stellar winds with remnant circumstel lar matter left over from the star formation process, the presence of which is also indicated by far-infrared (IRAS) and submm/mm continuum data.
