Abstract
Recently, several groups of young stars in the solar neighborhood have been discovered. Given their proximity, these systems are ideally suited for detailed studies of star and planet formation. Here we report on a group of young stars associated with the bright F8V star HD 199143. At a distance of only 48 pc, this is the closest YSO group containing a classical T Tauri star (HD 358623; K7-M0e). New ground-based mid-infrared data shows that both HD 199143 and HD 358623 have large infrared excesses due to circumstellar disks. A systematic search for new members of this Capricornius association has yielded four new probable members, which we use to derive an age of 5-10 Myr for the group as a whole.
