Dylan and from NAU in Flagstaff and Alejandro Reynoso from Monterey. Have both asked about what we can actually learn from the oscillation of stars. I'm going to tighten that question and say, what are you learning that we didn't otherwise figure out through other means. Why is that? Let me give the analogy with music again. So we have sound waves or happening inside the star, but the gas in the star is rotating around. And what do you get when you put a musician in a theater play and you make the podium rotate just for the fun of it as a surprise to the musician?"
