Physics

Scientific paper

We propose to obtain a Chandra/HETGS spectrum of IM Lup with an exposure of 150 ks. IM Lup is the only known X-ray bright transition object between the classical T Tauri star phase and the weak-lined T Tauri phase. IM Lup shows an IR excess, but its Halpha equivalent width is small, indicating very low accretion rates. The Chandra spectrum will provide important information on the accretion process during the last stages of disk dispersal and therefore the latest possible time for planet growth. We will study the abundance pattern, trace the plasma density in He-like triplets, enhance the observational findings with accretion shock simulations and relate our results to the long-standing problem of disk dispersal and angular momentum evolution in young stars.
