Revealing the Complex Outflow Structure of Binary UY Aurigae
15 May 2014: The following is duplicated from the Subaru press release, distributed on May 20, 2014. An international team of astronomers, led by Dr. Tae-Soo Pyo (Subaru Telescope, NAOJ), has revealed a complicated outflow structure in the binary UY Aur (Aurigae). The team observed the binary using the Gemini North's NIFS (Near-Infrared Integral Field Spectrometer) with the Altair adaptive optics system (Note 1). The team found that the primary star has a wide, open outflow, while the secondary star has a well-collimated jet. Because many stars form together as companions in binary or multiple systems, investigating these systems is essential for understanding star and planet formation. Although jets (i.e., narrow bright streams of gas) and outflows (i.e., less collimated flows of gas) from single young stars are ubiquitous, only a few observations have shown jets or outflows from multiple, low-mass young stars. Therefore, the current team chose to examine the outflow structure …
