Near-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 کاملGG 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 کاملSUBARCSECOND IMAGING AT 267 GHz OF A YOUNG BINARY SYSTEM: DETECTION OF A DUST DISK OF RADIUS LESS THAN 70 AU AROUND T TAURI N
The young binary system T Tauri was observed with the Owens Valley Millimeter Array in the 267 GHz continuum and HCO J 5 3–2 emission at 00.8 resolution, with the single-baseline interferometer of the James Clerk Maxwell Telescope–Caltech Submillimeter Observatory in the 357 GHz continuum and with the W. M. Keck Telescope at l 5 4 mm. The 267 GHz emission is unresolved, with a flux of mJy, loca...
متن کاملHigh Resolution VSOP Imaging of a Southern Blazar PKS 1921–293 at 1.6 GHz
We present a high resolution 1.6 GHz VSOP image of the southern blazar PKS 1921–293. The image shows a typical core–jet morphology, consistent with ground–based VLBI images. However, the addition of data from the space antenna has greatly improved the angular resolution (especially along the north–south direction for this source), and thus allowed us to clearly identify the core. Model fitting ...
متن کاملHigh Resolution Imaging using 325 GHz and 1.5 THz Transceivers
The Submillimeter-Wave Technology Laboratory (STL) at the University of Massachusetts Lowell has designed and constructed two high resolution terahertz imaging systems based on 325 GHz and 1.5 THz transceivers. While the systems were originally designed to acquire radar signatures of high fidelity scale models, their high sensitivity and high stability at 325 GHz and 1.5 THz make them novel sys...
