X-shooter spectroscopy of young stars with disks. The TW Hydrae association as a probe of the final stages of disk accretion
L. Venuti, B. Stelzer, J. M. Alcalá +9
We investigate ongoing accretion activity in young stars in the TW Hydrae association (TWA, ~8-10 Myr), an ideal target to probe the final stages of disk accretion down to brown dw…

Evidence for Variable, Correlated X-ray and Optical/IR Extinction toward the Nearby, Pre-main Sequence Binary TWA 30
David A. Principe, G. G. Sacco, Joel H. Kastner +2
We present contemporaneous XMM-Newton X-ray and ground-based optical/near-IR spectroscopic observations of the nearby ( pc), low-mass (mid-M) binary system TWA 30A an…

Accretion, disks, and magnetic activity in the TW Hya association
B. Stelzer, A. Frasca, J. M. Alcala
We present new photometric and spectroscopic data for the M-type members of the TW Hya association with the aim of a comprehensive study of accretion, disks and magnetic activity a…
