  1. CorMASS+Magellan • Science objective: IR spectroscopy of Spitzer sources • Least massive brown dwarfs • Proto-brown dwarfs • Brown dwarf companions • Serendipitous discoveries • Properties of CorMASS • Plans for Magellan

  2. The least massive brown dwarfs Spitzer+HST+Magellan current mid-90’s ? brown dwarfs stars Jupiter Sun

  3. Spitzer+IRAC (3-8 m): Chamaeleon I

  4. Spitzer+IRAC (3-8 m): Chamaeleon I CTIO 4 m (YJHK) HST+ACS (IZ)

  5. IR Spectroscopy of BD Candidates

  6. CorMASS+Magellan • CorMASS • Instrument team = John Wilson, Mike Skrutskie (UVa) • Capabilities = 0.8-2.5 m, cross-dispersed, R=300, f/9 • Previous telescopes = Palomar 60”, VATT, APO 3.5 m • On Magellan = 0.4x3” slit, SN=10 for K=18 in 1 hour • Ideal for followup of candidate brown dwarfs

  7. CorMASS+Magellan • CorMASS • Instrument team = John Wilson, Mike Skrutskie (UVa) • Capabilities = 0.8-2.5 m, cross-dispersed, R=300, f/9 • Previous telescopes = Palomar 60”, VATT, APO 3.5 m • On Magellan = 0.4x3” slit, SN=10 for K=18 in 1 hour • Ideal for followup of candidate brown dwarfs • Observing run on Magellan • ~8 nights in February or March 2005 • Queue observing for IRAC targets and other CfA proposed work • Harvard-only run now, but will advertise to partners up approval
