Query: HD 199143 and HD 358623: Two Recently Identified Members of the Beta
  Pictoris Moving Group   HD 199143 and HD 358623 (BD-17 6128) are two sets of binary stars which are
physically associated and 48 pc from Earth. We present heliocentric radial
velocities and high lithium abundances which establish these stars as members
of the 12 Myr-old Beta Pictoris Moving Group. We also present mid-IR
photometric measurements which show no firm evidence for warm dust around all
four stars.
