Abstract

We have used the Aladin sky atlas of the Virtual Observatory to look for new common proper-motion pairs in three young stellar kinematic groups: Local Association (Tau ˜ 10-120 Myr), Tucana-Horologium (Tau ˜ 30 Myr) and Beta Pictoris (Tau ˜ 12 Myr). We have found 9 new and 14 known common proper-motion companions to the 210 investigated stars. With the CAFOS instrument at the 2.2 m Calar Alto telescope, we have investigated in detail one of the new pairs, the HD 143809 AB system, which is formed by a bright G0V primary star and a previously unknown young M1.0-1.5Ve star.
