Abstract
HR 4049 is a peculiar evolved binary surrounded by a circumbinary disk. Mid- infrared observations show that the disk is rich in molecular gas and radially extended. To study the properties of this disk, we re-analyzed a set of near-infrared observations at high spectral resolution obtained with Gemini-Phoenix. These data cover absorption lines originating from the first overtone of CO and from H 2 O in the 2.3 μm region as well as more complex emission-absorption profiles from H 2 O and the fundamental mode of CO near ...
