Structure in the disc of epsilon Aurigae – analysis of ARCES and TripleSpec spectra from the 2010 eclipse

Worldwide interest in the recent eclipse of epsilon Aurigae resulted in the generation of several extensive data sets, including high-resolution spectroscopic data sets. This lead to the discovery, among other things, of the existence of a mass transfer stream, seen notably during third contact. We explored spectroscopic facets of the mass transfer stream during third contact, using high-resolutio...
