摘要：

We report techniques and results of a Palomar 200 inch (5 m) adaptive optics imaging survey of substellar companions to solar-type stars. The survey consists of K-s coronagraphic observations of 21 FGK dwarfs out to 20 pc (median distance similar to 17 pc). At 1 '' separation (17 projected AU) from a typical target system, the survey achieves median sensitivities 7 mag fainter than the parent star. In terms of companion mass, this corresponds to sensitivities of 50 M-J (1 Gyr), 70 M-J (solar age), and 75 M-J (10 Gyr), using the evolutionary models of Baraffe and colleagues. Using common proper motion to distinguish companions from field stars, we find that no system shows positive evidence of a previously unknown substellar companion (searchable separation similar to 20-250 projected AU at the median target distance).
