asteroseismology with Gaussian processes

After a low-research morning, Foreman-Mackey and I retreated to an undisclosed location to work on asteroseismology. We checked (by doing a set of likelihood evaluations) on behalf of Eric Agol (UW) whether there is any chance of measuring asteroseismological modes using a bespoke Gaussian process which corresponds to narrow Gaussians in the Fourier domain. The prospects are good (it seems to work) but the method seemed to degrade with signal-to-noise and sampling worse than I expected. Okay, enough playing around! Back to work.
