Abstract

We present the results of our UBV JHKLM photometric and spectroscopic observations of V407 Cyg obtained in 2003–2015. No fast brightness variations of V407 Cyg have been detected since its RS Oph-type outburst in 2010. Now the binary demonstrates a low-excitation emission spectrum with Hα weaker than the [N II] 6584 Å line. It is a typical spectrum on the way to the passive state.

Keywords: binaries: symbiotic; stars: variables: Miras; stars: individual: V407 Cyg
