  1. Robo-AO: Binarity Survey Nicholas Law

  2. Multiplicity in solar neighborhood • Various surveys • Solar type stars: • Duquennoy & Mayor (1991) • More recent RV surveys • Some AO BD surveys (eg. Gelino et al.) • All 100-200 targets • M-dwarfs • Lots of ~50-target AO surveys • RV surveys starting up for planet searches • Other types have a similar patchwork of surveys 5/17/2010 Astronomy Tea Talk 2

  3. Robo-AO’s contribution • 8 Target groups • A, F, G, K, M0-3, M3-6, M6-9, L0+ • Sensitivity • High-mass BD companions in ~120 secs (at large radii) • Main sequence companions at most separations • In visible, white dwarf companions reachable • CPM confirmation in 1 month is conceivable • Target numbers • 150 targets per night • Useful contribution in 5-8 nights @ 150 targets per target group • Large, coherent, well-understood-bias survey 5/17/2010 Astronomy Tea Talk 2
