Complex Outflow Structure of UY Aur

Jets and outflows are ubiquitous in single young stars, a regular feature of their formation process, but only a few examples in binary systems have been identified. Tae-Soo Pyo (Subaru Telescope, National Astronomy Observatory of Japan) and colleagues have used the Near-Infrared Integral Field Spectrometer (NIFS) on Gemini North with the Altair adaptive optics system to examine the binary UY Aurigae. At high spatial resolution, and with simultaneous spectroscopic information, this system reveals a complicated structure, including a wide, open outflow from the primary star and a well-collimated jet from the secondary, along with circumstellar and circumbinary disks. More information is available at Gemini, based on the Subaru Telescope press release, and the complete results are published in The Astrophysical Journal.
