EUV Emission from Sungrazing Comets
Abstract
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. The first step, however, is to explain why the comet produces the EUV emission. In this talk, I will outline a model that describes the interaction of the cometary atmosphere with the quiescent solar background and results in such emission. In particular, the model accurately predicts the temporal and wavelength response of the emission detected by SDO/AIA. After describing the emission process, I will go on to discuss what we can learn about the corona from these observations.
