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 کاملCaptured at millimeter wavelengths: a flare from the classical T Tauri star DQ Tauri
For several hours on 2008 April 19, the T Tauri spectroscopic binary DQ Tau was observed to brighten, reaching a maximum detected flux of 468 mJy and likely making it (briefly) the brightest object at 3 mm in the Taurus star-forming region. We present the light curve of a rarely before observed millimeter flare originating in the region around a pre-main-sequence star, and the first from a clas...
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...
