Dr. Etienne Artigau (Gemini-South) The widest Very Low-Mass binary system. I will discuss the recent discovery by our team of the widest very low mass binary (primary mass <0.1 Msol ) ever found with a projected separation of ~5100 AU, more than twice that of the widest previously known system. Near-infrared spectroscopy obtained with GNIRS at Gemini South indicates spectral types of M6.5V and M8V, and a photometric distance of ~62 pc. Given that previous studies have firmly established that no more than 1% of very low mass binary systems have orbits larger than 20 AU, the very existence of such a wide system challenges low-mass star formation and evolution models.
