A paper on epsilon Aurigae which makes extensive use of amateur spectra has been accepted for publication in MNRAS and is published on ArXiv today

The paper uses Equivalent Width and Radial Velocity data from high resolution spectra taken during eclipse to model the epsilon Aurigae system. The main conclusion is that the data favours the low mass over the high mass model.
