Arizona State Univ. astronomers have recently completed MinMs (M-dwarfs in Multiples) – a new survey of 245 late-K to mid-M dwarfs within 15 parsecs. The survey uses, in part, the MMT adaptive optics system and ARIES to search for binary star and brown dwarf companions at close separations from the host star. They found a total of 65 co-moving stellar companions, of which four are newly resolved in this study. MinMs provides a benchmark data set for understanding how often these low mass stars form with companions. Read more here.
