Sub - arcsec imaging of the AB Aur molecular disk and envelope at millimeter wavelengths : a non Keplerian disk
We present sub-arcsecond images of AB Auriga obtained with the IRAM Plateau de Bure interferometer in the isotopologues of CO, and in continuum at 3 and 1.3 mm. These observations allow us to trace the structure of the circumstellar material of AB Aur in regions where optical and IR imaging is impossible because of the emission from the star. These images reveal that the environment of AB Aur i...
متن کاملPossible Molecular Spiral Arms in the Protoplanetary Disk of AB Aur
The circumstellar dust disk of the Herbig Ae star AB Aur has been found to exhibit complex spiral-like structures in the near-IR image obtained with the Subaru Telescope. We present maps of the disk in both CO (3-2) and dust continuum at 345 GHz with the SMA at an angular resolution of 1 .0 × 0.7(144AU × 100AU). The continuum emission traces a dust disk with a central depression and a maximum o...
متن کاملUnraveling the Transitional Disk RX J1615.3-3255: Scattered Light Observations Versus Disk Models
We present a two-stage analysis of the transitional disk RX J1615.3-3255 located in the Lupus association (∼1 Myr old). Using 1.6 μm scattered light, polarized intensity images observed with the HiCIAO instrument of the Subaru Telescope, we deduce the position angle and the inclination angle. The disk is found to extend out to 92 ± 12 AU in the scattered light and no clear structure is observed...
متن کاملTHE DISK AROUND CoKu TAURI/4: CIRCUMBINARY, NOT TRANSITIONAL
CoKu Tau/4 has been labeled as one of the very few known transition disk objects—disks around young stars that have their inner disks cleared of dust, arguably as a result of planetary formation. We report aperture-masking interferometry and adaptive optics imaging observations showing that CoKu Tau/4 is in fact a near-equal binary star of projected separation ∼53 mas (∼8 AU). The spectral ener...
متن کاملThe Disk around Coku Tau / 4 : Circumbinary , Not Transitional
CoKu Tau/4 has been labeled as one of the very few known transition disk objects: disks around young stars that have their inner disks cleared of dust, arguably due to planetary formation. We report aperture-masking interferometry and adaptive optics imaging observations showing that CoKu Tau/4 is in fact a near-equal binary star of projected separation ∼53 mas (∼8 AU). The spectral energy dist...
