Title: Exploring the Structure of Brown Dwarf Disks

Abstract: Our recent observations with the TIMMI2/ESO3.6m resulted in the first ground based detection of a disk around a young brown dwarf candidate. These observations opened a new way to understand the formation of substellar objects via comparing their disks to those of T Tauri stars. One immediate lesson from the mid-infrared studies was the lack of the previously predicted silicate emission feature and thus the failure of the simple down-scaled T Tauri disk model for the only observed object. Taking advantage of the superb sensitivity of the T- RECs mid-infrared camera, we propose to target young BDs to detect specifically their disks and probe their silicate feature. These observations will show how general are the surprising properties of the best known BD disk.
