  ABSTRACT: An unprecedented array of astronomical observatories were brought to bear on the 2006 outburst of RS Ophiuchi. Many calculations and values derived from these measurements are sensitive to the distance. Historically, the distance to RS Oph has fallen in the range 0.5 to >5 kpc with distances in the low end of this range asserted during later epochs. We survey the literature prior to 2006 and review the various approaches taken to determine distances. We report discussion of this issue from the current epoch and make recommendations for further measurements and calculations to bound the distance. Lastly, we report that for the 2006 outburst, the canonical distance is 1.4 ^{+0.6}_{-0.2} kpc.

  ABSTRACT: We present further Spitzer Space Telescope observations of the recurrent nova RS Ophiuchi, obtained over the period 208-430 days after the 2006 eruption. The later Spitzer IRS data show that the line emission and free-free continuum emission reported earlier is declining, revealing incontrovertible evidence for the presence of silicate emission features at 9.7 and 18microns. We conclude that the silicate dust survives the hard radiation impulse and shock blast wave from the eruption. The existence of the extant dust may have significant implications for understanding the propagation of shocks through the red giant wind and likely wind geometry.
