Scientific paper

We present 150 ks Chandra/HETGS observations of a group of young stars comprising a Herbig Ae star (HD 102437), three T Tauri stars (one classical T Tauri star, and two weak-lined T Tauri stars), and a supposed brown dwarf. The HETG spectrum of the Herbig Ae star shows strong emission lines corresponding to a wide range of plasma temperatures; spectral diagnostics provide clues to the yet unestablished X-ray production mechanisms in young intermediate mass stars. We also present 0th order spectra, obtained for all group members.
