Using Comets as Solar Probes

The EUV emission resulting from comets' passage through the solar atmosphere has opened many exciting avenues of study. The observations show the sublimated cometary material to interact with ambient magnetic field and highlight magnetic features that are not normally visible with EUV telescopes. In this talk, I will outline a model that describes the interaction of the cometary atmosphere with the quiescent solar background and results in EUV emission. After describing the emission process, I will go on to discuss what we have learned about the corona from these observations and speculate on what else comets can teach us about the Sun.
