Misalignment of Outflow Axes in the Proto-Multiple Systems in Perseus
  We investigate the alignment between outflow axes in nine of the youngest
binary/multiple systems in the Perseus Molecular Cloud. These systems have
typical member spacing larger than 1000 AU. For outflow identification, we use
12CO(2-1) and 12CO(3-2) data from a large survey with the Sub- millimeter
Array: Mass Assembly of Stellar Systems and their Evolution with the SMA
(MASSES). The distribution of outflow orientations in the binary pairs is
consistent with random or preferentially anti-aligned distributions,
demonstrating that these outflows are misaligned. This result suggests that
these systems are possibly formed in environments where the distribution of
angular momentum is complex and disordered, and these systems do not come from
the same co-rotating structures or from an initial cloud with aligned vectors
of angular momentum.
