High resolution 2.7 mm observations of L1551 IRS5: A protobinary system?

We present sub-arcsecond resolution imaging of the λ=2.7 mm continuum emission from the young, embedded system L1551 IRS5 using the new, nine element, high resolution configuration of the BIMA array. The observed emission arises from two compact sources separated by 0.35 and coincident with the two sources seen at λ=2 cm. The data support the view that IRS 5 is a protobinary system with separation of ∼50 AU and individual circumstellar disks.
