N2 - Results of spectral observations of the unique eclipsing binary e{open} Aur obtained during its recent eclipse are presented. Profile variations of many spectral lines at different eclipse phases can be traced. These variations are partly due to absorption of the stellar radiation in a rotating disk of gas and dust around the second component and partly due to geometric screening of the stellar photosphere and circumstellar region by the disk. A comparison of these results with analogous results obtained by Lambert and Sawyer during the previous (1982-1984) eclipse of e{open} Aur indicates good agreement, suggesting stability of the gas-dust disk surrounding the invisible component in the binary. The masses of the binary components are estimated using new observational data. © 2013 Pleiades Publishing, Ltd.
