A Young Brown Dwarf Companion to DH Tauri
Yoichi Itoh, Masahiko Hayashi, Motohide Tamura +20
We present the detection of a young brown dwarf companion DH Tau B associated with the classical T Tauri star DH Tau. Near-infrared coronagraphic observations with CIAO on the Suba…
A near-infrared study of the NGC 7538 star forming region
D. K. Ojha, M. Tamura, Y. Nakajima +11
We present sub-arcsecond (FWHM ~ 0".7), NIR JHKs-band images and a high sensitivity radio continuum image at 1280 MHz, using SIRIUS on UH 88-inch telescope and GMRT. The NIR survey…
High resolution imaging polarimetry of HL Tau and magnetic field structure
P. W. Lucas, Misato Fukagawa, Motohide Tamura +10
We present high quality near infrared imaging polarimetry of HL Tau at 0.4 to 0.6 arcsec resolution, obtained with Subaru/CIAO and UKIRT/IRCAM. 3-D Monte Carlo modelling with align…
Flared Disks and Silicate Emission in Young Brown Dwarfs
Subhanjoy Mohanty, Ray Jayawardhana, Antonella Natta +3
We present mid-infrared photometry of three very young brown dwarfs located in the Ophiuchi star-forming region -- GY5, GY11 and GY310 --obtained with the Subaru 8-meter telesc…
