We discover that the very low-mass brown dwarf OTS 44 (M9.5, similar to 12 M-Jup) has significant accretion and a substantial disk, which demonstrates that the processes that accompany canonical star formation occur down to a central mass of a few Jupiter masses. We discover in VLT/SINFONI spectra that OTS 44 has strong, broad, and variable Pa beta emission that is evidence for active accretion at the planetary border. We also detect strong Ha emission of OTS 44 in a literature spectrum and…

First millimeter detection of the disk around a young, isolated, planetary-mass object
OTS44 is one of only four free-floating planets known to have a disk. We have previously shown that it is the coolest and least massive known free-floating planet (∼12 ) with a substantial disk that
ALMA Discovery of a Disk around the Planetary-mass Companion SR 12 c
We report an Atacama Large Millimeter/submillimeter Array 0.88 mm (Band 7) continuum detection of the accretion disk around SR 12 c, an ∼11 M Jup planetary-mass companion (PMC) orbiting its host
Erratum: Accretion signatures in the X-shooter spectrum of the substellar companion to SR12
About a dozen substellar companions orbiting young stellar objects or pre-main sequence stars at several hundred au have been identified in the last decade. These objects are interesting both due to
VARIABILITY IN A YOUNG, L/T TRANSITION PLANETARY-MASS OBJECT
As part of our ongoing NTT SoFI survey for variability in young free-floating planets and low-mass brown dwarfs, we detect significant variability in the young, free-floating planetary-mass object
Strong Hα emission and signs of accretion in a circumbinary planetary mass companion from MUSE
Context. Intrinsic Hα emission can be advantageously used to detect substellar companions because it improves contrasts in direct imaging. Characterising this emission from accreting exoplanets
AN ALMA CONSTRAINT ON THE GSC 6214-210 B CIRCUM-SUBSTELLAR ACCRETION DISK MASS
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of GSC 6214-210 A and B, a solar-mass member of the 5–10 Myr Upper Scorpius association with a 15 ± 2 MJup companion
Herschel/PACS view of disks around low-mass stars and brown dwarfs in the TW Hydrae association
We conducted Herschel/PACS observations of five very low-mass stars or brown dwarfs located in the TW Hya association with the goal of characterizing the properties of disks in the low stellar mass
ACCRETION ONTO PLANETARY MASS COMPANIONS OF LOW-MASS YOUNG STARS
Measurements of accretion rates onto planetary mass objects may distinguish between different planet formation mechanisms, which predict different accretion histories. In this Letter, we use Hubble
Accretion onto Pre-Main-Sequence Stars
Accretion through circumstellar disks plays an important role in star formation and in establishing the properties of the regions in which planets form and migrate. The mechanisms by which
Observing the gas component of circumplanetary disks around wide-orbit planet-mass companions in the (sub)mm regime
Context. Several detections of wide-orbit planet-mass/substellar companions around young solar-like stars were reported in the last decade. The origin of those possible planets is still unclear, but

TLDR
Spectro-astrometric data that spatially resolve an outflow from a brown dwarf suggests that the outflow mechanism is universal, and perhaps relevant even to the formation of planets.
