Exploring brown dwarf disks.

NATTA A. and TESTI L.

Abstract (from CDS):

We discuss the spectral energy distribution of three very low mass objects in Chamaeleon I for which ground-based spectroscopy and photometry as well as ISO measurements in the mid-infrared are available (Comeron et al., 2000A&A...359..269C; Persi et al., 2000A&A...357..219P). One of these stars (Cha Hα1) is a bona-fide brown dwarf, with mass 0.04-0.05M. We show that the observed emission is very well described by models of circumstellar disks identical to those associated to T Tauri stars, scaled down to keep the ratio of the disk-to-star mass constant and to the appropriate stellar parameters. This result provides a first indication that the formation mechanism of T Tauri stars (via core contraction and formation of an accretion disk) extends to objects in the brown dwarf mass range.
