Field zero-age main-sequence stars in the solar neighbourhood: where have they come from.

WICHMANN R. and SCHMITT J.H.M.M.

Abstract (from CDS):

In the course of an all-sky survey for young stars in the solar neighbourhood, we have found a tight kinematic group of 10 F-G type zero-age main-sequence stars in the field. Here we discuss the origin of these stars. Backtracking the space motions of these stars, we argue that likely candidates for the parent association are the Perseus OB3 (Per OB3), Upper Centaurus-Lupus (UCL) and Lower Centaurus-Crux (LCC) associations, and that we are witnessing the ongoing diffusion of (at least one of) these associations into the field.
