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 .
