The TW Hydrae association: discovery of T Tauri star members near HR 4796.

ZUCKERMAN B., WEBB R.A., SCHWARTZ M. and BECKLIN E.E.

Abstract (from CDS):

We have identified six T Tauri stars, at least three of which are double, that are members of the nearest region of recent star formation, the TW Hydrae association. The newly discovered systems are mostly located south and east of and farther from Earth than most previously known members; thus, the full extent of the association is not yet established. Including secondaries in multiple star systems, the association is now known to include more than 30 T Tauri stars and a brown dwarf. We compare the TW Hydrae association to four other young nearby associations.
