Abstract
The Aladin sky atlas of the Virtual Observatory has shown to be a powerful and easy-handling tool for the discovery, confirmation, and characterization of high proper-motion, multiple stellar systems of large separation in the solar vicinity. Some of these systems have very low mass components (at the star/brown dwarf boundary) and are amongst the least bound systems found to date. With projected physical separations of up to tens of thousands astronomical units, these systems represent a challenge for theoretical scenarios of formation of very low-mass stars and brown dwarfs. Here we show preliminary results of a novel virtual search of binary systems and companions to Luyten stars with proper motions between 0.5 and 1.0 arcsec a− 1.
