All of the young star-forming regions are distant (d > 120 pc), making it difficult to resolve structure on the scale of disks ( ˜ 10-100 AU) and jets (? AU). Furthermore, examining these structures around low-mass objects is especially prohibitive since these objects are intrinsically faint. However, recent identification of the nearby, young ( ˜10; Myr) TW Hydrae Association (TWA) has ameliorated this situation. With only 24 systems, the TWA offers unique case studies at a critical time in disk evolution and planet-building processes. We have searched for additional low-mass members using the 2MASS database, and we present our current results, including three new members.
