Abstract

We present Spitzer spectroscopy of the recurrent nova RS Ophiuchi obtained on several occasions between 2006 and 2009. The spectra show variability in the silicate dust features at 9.7 μm and 18 μm, which form in the wind of the red giant in the system. We fit the spectra with Dusty models and find changes in the dust temperature, due to changes in the luminosity of the central source. The mass-loss rate of the secondary is a few 10^-7 M _⊙yr^-1, typical of a red giant of its type.
