Nicmos Observations of Gg Tau's Circumbinary Disk
GG Tau is an ideal system for studying the structure of a circumbinary disk. Separated by 0.0025 (35 AU at d=140pc; Ghez et al. 1993, AJ 106), the stellar components of the binary are surrounded by a massive disk. Originally detected through thermal dust emission at millimeter wavelengths (Dutrey et al. 1994, A&A 286; Guilloteau et al. 1999, A&A in press), the disk was subsequently imaged in sc...
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 کاملNICMOS images of the GG Tau Circumbinary Disk
We present deep, near-infrared images of the circumbinary disk surrounding the pre–main-sequence binary star, GG Tau A, obtained with NICMOS aboard the Hubble Space Telescope. The spatially resolved proto-planetary disk scatters ∼1.5% of the stellar flux, with a near-to-far side flux ratio of ∼1.4, independent of wavelength, and colors that are comparable to the central source all of these prop...
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 کاملCircumbinary Disk evolution
We study the evolution of circumbinary disks surrounding classical T Tau stars. High resolution numerical simulations are employed to model a system consisting of a central eccentric binary star within an accretion disk. The disk is assumed to be infinitesimally thin, however a detailed energy balance including viscous heating and radiative cooling is applied. A novel numerical approach using a...
