Today I had a great conversation with Lily Zhao (Yale) and Megan Bedell (Flatiron) about Zhao's projects for the semester at Flatiron that she is starting this moth. We have projects together in spectrograph calibration, radial-velocity measurement, and time-variability of stellar spectra. On that last part, we have various ideas about how to see the various kinds of variability we expect in the joint domain of wavelength and time. And since we have a data-driven model (wobble) for stellar spectra under the assumption that there is no time variability, we can look for the things we seek in the residuals (in the data space) away from that time-independent model. We talked about what might be the lowest hanging fruit and settled on p-mode oscillations, which induce radial-velocity variations but also brightness and temperature variations. I hope this works!
