I had a nice conversation today with Laura Kreidberg (MPIA) and Jason Dittmann (MPIA) about projects in ultra-precise spectroscopy for exoplanet-atmosphere science. I was pushing for projects in which we get closer to the metal (moving spectroscopy to two dimensions), and in which we use theoretical ideas to improve extraction of very weak spectral signals. Kreidberg was pushing for projects in which we use planet kinematics to separate very weak planet signals from star signals. On the latter, I recommended starting with co-ads of residuals.
