[53.02] High Resolution \lambda = 2.7 mm Observations of L1551 IRS5: A Protobinary System?

L. W. Looney, L. G. Mundy (U. of MD), W. J. Welch (RAL, UCB)

We present sub-arcsecond resolution imaging of the \lambda = 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\farcs35 and coincident with the two sources seen at \lambda = 2 cm. The data support the view that IRS 5 is a protobinary system with separation of \sim50 AU and individual circumstellar disks. The approximate masses of the disks are 0.024 M_\sun for the northern source and 0.009 M_\sun for the southern source.
