12 May 2003 | Journal: | Astrophys.J. 590 (2003) L111-L114 | Subject: | astro-ph | Affiliation: | MPIA), D. Apai (MPIA), Th. Henning (MPIA), and C. P. Dullemond (MPA | Abstract: | The combination of mid-infrared and recent submm/mm measurements allows us to set up the first comprehensive spectral energy distribution (SED) of the circumstellar material around a young Brown Dwarf. Simple arguments suggest that the dust is distributed in the form of a disk. We compare basic models to explore the disk parameters. The modeling shows that a flat disk geometry fits well the observations. A flared disk explains the SED only if it has a puffed-up inner rim and an inner gap much larger than the dust sublimation radius. Similarities and differences with disks around T Tauri stars are discussed. | Source: | arXiv, astro-ph/0305195 | Services: | Forum | Review | PDF | Favorites |
