Lily Zhao (Flatiron), Megan Bedell (Flatiron), and I spoke about our linear regression methods for EPRV today. Our methods are called Hamlet and Horatio for reasons we have trouble articulating. But the idea is that if the confusing spectral variability in EPRV comes from surface features rotating in and out of view on the stellar surface, that should impart structure to the data that we can grab and exploit. We stepped back and asked what are the real, underlying assumptions of these methods. We didn't come to extremely clear positions, I am afraid. The future of this field, IMHO, is Doppler imaging spectroscopy of the entire rotating, evolving stellar surface!
