A New, Young, Low-Mass Spectroscopic Binary Without a Home

摘要

We have discovered that 2MASS 08355977-3042306 is an accreting K7, doublelined, spectroscopic binary younger than ~20 Myr. The age of a dispersed young star can best be determined if it is a member of a known young moving group. However, the three dimensional space velocities (UVW) we calculate using radial velocity measurements, proper motions, and plausible photometric distances make membership in any known young moving group unlikely.
