		| Abstract: | 
		We present results from an on-going search for stellar and substellar companions with the Palomar 200″ adaptive optics system. We have observed 12 sources with a coronagraph and present detection limits for faint companions. From non-coronagraphic imaging, we find that 8 of 20 observed stars are probable binaries. The objects are taken from the Meyer et al. (2001) SIRTF (Spitzer) Legacy Science Team sample. JHK s and 10 μm photometry is used to set upper limits on the presence of dust disks.  |
