Disks in Brown Dwarf Systems
Published online by Cambridge University Press: 26 May 2016
Abstract
We discuss evidence for and properties of disks associated with brown dwarfs in the star-forming region ρ Oph. We derived photospheric parameters from low resolution near infrared spectroscopy and modeled the mid-infrared excess of nine substellar object candidates in the ρ OphISOCAM survey of Bontemps et al. (2001). In all cases, the mid-infrared excess is consistent with the SED expected from irradiated disks. These results suggest that circumstellar disks are commonly associated to young brown dwarfs and planetary-mass objects. Finally, we discuss the possibility of using these data to discriminate between various formation scenarios for substellar objects.
