Resolved ALMA continuum image of the circumbinary ring and circumstellar
  disks in the L1551 IRS 5 system
  L1551 IRS 5 is a FUor-like object located in the Taurus star forming region.
We present ALMA 1.3 mm continuum observations using a wide range of baselines.
The observations recovered the two circumstellar disks composing the system
and, for the first time, resolved the circumbinary ring. We determined the
geometry and estimated lower mass limits for the circumstellar disks using
simple models. We calculated lower limits for the total mass of both
circumstellar disks. After subtracting the two circumstellar disk models from
the image, the residuals show a clearly resolved circumbinary ring. Using a
radiative transfer model, we show that geometrical effects can explain some of
the brightness asymmetries found in the ring. The remaining features are
interpreted as enhancements in the dust density.
