X-ray Investigations of Young Stars Near Earth

The rapidly growing number of known young (age ∼8--100 Myr) stars within ∼100 pc of Earth offer unparalleled opportunities to investigate the early evolution of low-to intermediate-mass stars and the dispersal of planet-forming disks. I will present results from our ongoing XMM and Chandra studies of known and candidate members of nearby, young moving groups (NYMGs). Targeted and serendipitous X-ray observations of M-type NYMG members reveal the magnetic activity levels of very low-mass stars during their post-T Tauri evolutionary stages. Simultaneous X-ray and near-infrared spectroscopy campaigns targeting T Cha and TWA 30A, both of which are viewed through inclined, dusty accretion disks, provide insight into the compositions and clumpiness of these highly evolved disks.
