An ALMA disk mass for the candidate protoplanetary companion to FW Tau
We present ALMA observations of the FW Tau system, a close binary pair of M5 stars with a wide-orbit (300AU projected separation) substellar companion. The companion is extremely faint and red in the optical and near-infrared, but boasts a weak far-infrared excess and optical/near-infrared emission lines indicative of a primordial accretion disk of gas and dust. The component-resolved 1.3 mm continuum emission is found to be associated only with the companion, with a flux (1.78 ± 0.03 mJy) that...[Show more]
