Scientific paper

Young stellar systems in the solar neighborhood provide valuable laboratories for detailed studies of star and planet formation. We present high-resolution near-infrared images of some of the nearest young stars known, including candidate members of the TW Hydrae Association, obtained with the adaptive optics system on the Keck II 10-meter telescope. Our observations reveal binary companions with angular separations as small as 60 milli-arcseconds, or physical separations of 3 AU. These stellar systems are prime targets for follow-up spectroscopic and astrometric observations and for deep imaging searches for young planets.
