Using the largest high-resolution spectroscopic sample to date of young, very low mass stars and brown dwarfs, we investigate disk accretion in objects ranging from just above the hydrogen-burning limit all the way to nearly planetary masses. Our 82 targets span spectral types from M5 to M9.5, or masses from 0.15 M? down to about 15 jupiters. They are confirmed members of the ? Ophiuchus, Taurus, Chamaeleon I, IC 348, R Coronae Australis, Upper Scorpius, and TW Hydrae star-forming regions and… Expand

Spectroscopy of Young Planetary Mass Candidates with Disks
It is now well established that many young brown dwarfs exhibit characteristics similar to classical T Tauri stars, including infrared excess from disks and emission lines related to accretion.Expand

Accretion in rho-Ophiuchi brown dwarfs: infrared hydrogen line ratios
Mass accretion rate determinations are fundamental for an understanding of the evolution of pre-main sequence star circumstellar disks. Magnetospheric accretion models are used to derive values ofExpand

Context. Whilst there is a generally accepted evolutionary scheme for the formation of low‐mass stars, the analogous processes when moving down in mass to the brown dwarfs regime are not yet wellExpand
Searching for proto-brown dwarfs: Extending near IR spectroscopy of protostars below the hydrogen burning limit†
Recent observations of nearby star forming regions have offered evidence that young brown dwarfs undergo a period of mass accretion analogous to the T Tauri phase observed in young stars. Brown dwarfExpand
Accretion in brown dwarfs down to nearly planetary masses
We show that in accreting ultra low-mass stars and brown dwarfs, the CaII λ 8662 emission line flux correlates remarkably well with the mass accretion rate (), just as it does in higher massExpand

X-shooter spectroscopy of young stars with disks
We investigate ongoing accretion activity in young stars in the TW Hydrae association (TWA, ~8-10 Myr), an ideal target to probe the final stages of disk accretion down to brown dwarf masses. OurExpand
