Disks around Young Brown Dwarfs
We present some results from a systematic survey for disks around spectroscopically identified young brown dwarfs and very low mass stars. We find that ≈75% of our sample show intrinsic IR excesses, indicative of circum(sub)stellar disks. The observed excesses are well-correlated with Hα emission, consistent with a common disk accretion origin. Because the excesses are modest, conventional anal...
متن کاملLooking for outflows from brown dwarfs
First evidences of IR excess and disk mass accretion (strong Hα emission) around brown dwarfs seem to indicate the existence of circumstellar disks around these sub-stellar objects. Nothing is known at the present time about outflows which potentially might be launched from brown dwarfs, although jets are typically associated with the accretion in standard T Tauri star disks. In this paper we c...
متن کاملProplyds and Massive Disks in the Orion Nebula Cluster Imaged with CARMA and SMA
We imaged a 2 × 2 region of the Orion Nebula cluster in 1.3 mm wavelength continuum emission with the recently commissioned Combined Array for Research in Millimeter Astronomy (CARMA) and with the Submillimeter Array Miller Institute for Basic Research in Science, Berkeley, CA 94720 Steward Observatory, University of Arizona, Tucson, AZ 85721
متن کاملThe Role of Thermal Conduction in Accretion Disks with Outflows
In this work we solve the set of hydrodynamical equations for accretion disks in the spherical coordinates (r,θ,ϕ) to obtain the explicit structure along θ direction. We study a two-dimensional advective accretion disc in the presence of thermal conduction. We find self-similar solutions for an axisymmetric, rotating, steady, viscous-resistive disk. We show that the global structure of an advec...
متن کاملFlared Disks and Silicate Emission in Young Brown Dwarfs
We present mid-infrared photometry of three very young brown dwarfs located in the ρ Ophiuchi star-forming region – GY5, GY11 and GY310 – obtained with the Subaru 8-meter telescope. All three sources were detected at 8.6 and 11.7μm, confirming the presence of significant mid-infrared excess arising from optically thick dusty disks. The spectral energy distributions of both GY310 and GY11 exhibi...
