New Binary Systems in the Northern Sky from the SUPERBLINK Survey
Abstract
More than half of all stars are believe to a part of a binary or multi-star system. Our search of proper motion objects from the SUPERBLINK survey has uncovered numerous pairs of co-moving stars, a significant fraction of which are revealed to be resolved, wide binaries within 100pc of the Sun. The pairs were identified from the SUPERBLINK database of northern stars with proper motions of 0.04 seconds of arc per year or larger. Wide binaries were found by looking for pairs of stars within 2 minutes of arc from each other and with proper motions comparable to within the measurement errors. For pairs in which one of the stars has an accurate distance measurement, this provides an instant determination of the companion's distance from the Sun. Some interesting new binaries are presented.
