We are conducting a Jansky VLA Ka-band ( 8 mm and 1 cm ) and C-band ( 4 cm and 6.4 cm ) survey of all known protostars in the Perseus Molecular Cloud , providing resolution down to \sim 0 \farcs 06 and \sim 0 \farcs 35 in Ka-band and C-band , respectively .
Here we present first results from this survey that enable us to examine the source NGC 1333 IRAS2A in unprecedented detail and resolve it into a proto-binary system separated by 0 \farcs 621 \pm 0 \farcs 006 ( \sim 143 AU ) at 8 mm , 1 cm , and 4 cm .
These 2 sources ( IRAS2A VLA1 and VLA2 ) are likely driving the two orthogonal outflows known to originate from IRAS2A .
The brighter source IRAS2A VLA1 is extended perpendicular to its outflow in the VLA data , with a deconvolved size of 0 \farcs 055 ( \sim 13 AU ) , possibly tracing a protostellar disk .
The recently reported candidate companions ( IRAS2A MM2 and MM3 ) are not detected in either our VLA data , CARMA 1.3 mm data , or SMA 850 µm data .
SMA CO ( J = 3 \rightarrow 2 ) , CARMA CO ( J = 2 \rightarrow 1 ) , and lower resolution CARMA CO ( J = 1 \rightarrow 0 ) observations are used to examine the outflow origins and the nature of the candidate companions to IRAS2A VLA1 .
The CO ( J = 3 \rightarrow 2 ) and ( J = 2 \rightarrow 1 ) data show that IRAS2A MM2 is coincident with a bright CO emission spot in the east-west outflow , and IRAS2A MM3 is within the north-south outflow .
In contrast , IRAS2A VLA2 lies at the east-west outflow symmetry point .
We propose that IRAS2A VLA2 is the driving source of the East-West outflow and a true companion to IRAS2A VLA1 , whereas IRAS2A MM2 and MM3 may not be protostellar .
