GG Tauri: the ring world
We present sub-arcsecond images of the mm dust emission and 13CO J=2–1 line emission in the young quadruple system GG Tau. These observations unambiguously resolve the circumbinary disk of the close (∼ 0.3′′) binary system into two distinct components: an extremely dense, sharp-edged ring, surrounded by an extended disk. Continuum emission is also detected from the center of this structure; it ...
متن کاملNear-Infrared Imaging Polarimetry of the GG Tauri Circumbinary Ring.
We present 1 µm Hubble Space Telescope/near-infrared camera and multiobject spectrometer resolved imaging polarimetry of the GG Tau circumbinary ring. We find that the ring displays east-west asymmetries in surface brightness as well as several pronounced irregularities but is smoother than suggested by ground-based adaptive optics observations. The data are consistent with a 37 degrees system ...
متن کاملACS Images of the GG Tauri Circumbinary Disk
Hubble Space Telescope Advanced Camera for Surveys images of the young binary GG Tauri and its circumbinary disk in V and I bandpasses were obtained in 2002 and are the most detailed of this system to date. They confirm features previously seen in the disk including: a " gap " apparently caused by shadowing from circumstellar material; an asymmetrical distribution of light about the line of sig...
متن کاملHST/WFPC2 Images of the GG Tauri Circumbinary Disk
We present the first visible wavelength images of the GG Tauri circumbinary ring, obtained with the Hubble Space Telescope’s Wide Field and Planetary Camera 2. Scattered light from the ring is detected in both V and I band images. The images show that the ring is smooth, except for a small gap that could be a shadow caused by material between the stars and the ring. The spokes seen extending fr...
متن کاملDetection of H2 Pure Rotational Line Emission from the Gg Tauri Binary System
We present the first detection of the low-lying pure rotational emission lines of H2 from circumstellar disks around T Tauri stars, using the Short Wavelength Spectrometer on the Infrared Space Observatory. These lines provide a direct measure of the total amount of warm molecular gas in disks. The S(0) line at 28.218 J 5 2 r 0 mm and the S(1) line at 17.035 mm have been observed toward the dou...
