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 targets
M-dwarfs
Lots of ~50-target AO surveys
RV surveys starting up for planet searches
Other types have a similar patchwork of surveys

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 targets per target group
Large, coherent, well-understood-bias survey
