Centimeter Emission in the UY Aur System. (2006). Revista Mexicana De Astronomía Y Astrofísica, 42(1), 15-18. https://astronomia.unam.mx/journals/rmxaa/article/view/2006rmxaa..42...15c

Abstract

We report 3.6 cm continuum observations taken with the Very Large Array (VLA) of the young binary system UY Aur. The binary consists of a T Tauri star, UY Aur A, and a so-called ``infrared companion'' (IRC), UY Aur B, separated by 0".89. UY Aur is an interesting system because it shows observational features whose origin is not well understood. One of them is the unusual low spectral index found in the millimeter region. In our VLA study, we have detected centimeter continuum radiation that coincides with the reported positions at 1.3 and 2.7mm and is consistent with the optical position of UY Aur. We conclude that the 3.6 cm emission is associated with the binary system. Furthermore, we suggest that the centimeter emission might be related to a previously reported bipolar outflow.
