I recently wrote some MCMC software from scratch for analysing the orbits of binary stars. The observational data are extracted from Kepler photometry, by quantifying phase shifts in stellar pulsations. I also investigate the interior rotation rates of stars using the same photometry, by looking for periodic patterns in the g mode pulsations of γ Doradus stars. Rotational splittings in the oscillation frequencies reveal the rotation rate of the stellar core. Repeating this analysis for a large number of stars allows the angular momentum profiles of intermediate-mass stars to be mapped across a variety of stellar properties.
