Fig. 18.— Model fitting KY Cyg. The solid black shows the fluxed spectrum obtained<br />
as part <strong>of</strong> the 2.1-m GoldCam observing described here. The dotted line shows the best<br />
fit model, with an effective temperature <strong>of</strong> 3500 K and a log g=-1.0 [cgs]. The study by<br />
Levesque et al. (2005) showed that this was one <strong>of</strong> the largest stars known. The extra flux<br />
in the star in the far blue is due to scattering by circumstellar dust.
