TL;DR
This study uses submillimeter observations to detect and analyze the disk around the brown dwarf KPNO Tau 3, revealing its mass and properties, and comparing it to disks around low-mass stars.
Contribution
First direct measurement of the disk mass and properties around KPNO Tau 3, supporting the idea that brown dwarf disks are similar to those of low-mass stars.
Findings
KPNO Tau 3 has a disk mass of approximately 4.0 x 10^{-4} M_sun.
No significant disks detected around KPNO Tau 1 and KPNO Tau 6.
Disk properties of KPNO Tau 3 are consistent with low-mass star disks.
Abstract
We present submillimeter observations of the young brown dwarfs KPNO Tau 1, KPNO Tau 3, and KPNO Tau 6 at 450 micron and 850 micron taken with the Submillimeter Common-User Bolometer Array on the James Clerke Maxwell Telescope. KPNO Tau 3 and KPNO Tau 6 have been previously identified as Class II objects hosting accretion disks, whereas KPNO Tau 1 has been identified as a Class III object and shows no evidence of circumsubstellar material. Our 3 sigma detection of cold dust around KPNO Tau 3 implies a total disk mass of (4.0 +/- 1.1) x 10^{-4} Msolar (assuming a gas to dust ratio of 100:1). We place tight constraints on any disks around KPNO Tau 1 or KPNO Tau 6 of <2.1 x 10^{-4} Msolar and <2.7 x 10^{-4} Msolar, respectively. Modeling the spectral energy distribution of KPNO Tau 3 and its disk suggests the disk properties (geometry, dust mass, and grain size distribution) are consistent…
