First JCMT Gould Belt Survey results on multiple systems Jenny Hatchell U Exeter, Exeter, UK
I will present first results from the JCMT Gould Belt Survey on multiple systems. With 8 arcsec resolution at 450 microns, SCUBA-2 can separate sources at 2000 AU at the typical Gould Belt distance of 250 pc (1000 AU in Ophiuchus and Taurus), providing a stepping stone to interferometer resolution. These systems are interesting, NOT because they will harden to form gravitationally bound binaries but because with time they should evolve to WIDER systems (through 3-body interactions and dissipative interactions with gas), with at least one partner in the process moving through the evolutionary classes. Starting with Serpens/Aquila, I will look at the statistics of Class 0 and even prestellar systems with the IRAS-based "Class I" binarity in this separation range, and consider what these systems tell us about the evolution of protostars which share a common mass reservoir.
