TY  - JOUR
AB  - We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetarymasscompanion at a projected separation of about 40 au. We detect emission from dust continuum at 0.89 mm andfrom the J = 3 - 2 rotational transition of CO from a very compact disk around the young brown dwarf. Thesmall radius found for this brown dwarf disk may be due to truncation from the tidal interaction with the planetarymasscompanion. Under the assumption of optically thin dust emission, we estimate a dust mass of 0.1 M⊕ for the2M1207A disk and a 3σ upper limit of ∼1 MMoon for dust surrounding 2M1207b, which is the tightest upper limitobtained so far for the mass of dust particles surrounding a young planetary-mass companion. We discuss theimpact of this and other non-detections of young planetary-mass companions for models of planet formationthat predict circumplanetary material to surround these objects.
