Today Rachael Roettenbacher (Yale) gave the CCA Colloquium, on Doppler imaging and interferometry and other methods for imaging stellar surfaces. In conversations with Roettenbacher and others (including Lily Zhao at Yale and Megan Bedell and Rodrigo Luger at Flatiron), I'm coming around to the position that extremely precise radial-velocity measurements of stars will require accurate models of rotating, spotty, time-evolving stellar surfaces. At the end of her talk, there were some discussions about this point: Should EPRV surveys be associated with stellar surface imaging campaigns? Probably, if we want to characterize true Earth analogs!
