Description
LP 714-37 was identified by Phan-Bao et al. as one of the very few wide
pairs of very low mass (VLM) stars known to date, with a separation of
33 AU. Here we present adaptive optics imaging that resolves the
secondary of the wide pair into a tighter binary, with a projected
angular separation of 0.36", or 7 AU. The estimated spectral types of LP
714-37B and LP 714-37C are M8.0 and M8.5, respectively. We discuss the
implications of this finding for brown dwarf formation scenarios.
Based on observations made at the Canada-France-Hawaii Telescope,
operated by the National Research Council of Canada, the Centre National
de la Recherche Scientifique de France, and the University of Hawaii.
