Listening to the Stars: Kepler and the Asteroseismic Revolution

The Kepler mission, while nominally a planet-hunting mission, has given us an unprecedented view of the stars. The same instrumental precision that allows the spacecraft to detect the faint signature of a transiting planet has also revealed the dynamic lives of stars themselves: the presence and movement of star spots, convection, and propagation of sound waves. The study of these waves, known as asteroseismology, allows us to look in to the deep, invisible interior of stars. I will describe how these new data have fundamentally changed the way we study stars - how the view of the interior they provide allows us to test our stellar models in ways never before possible, and how we can use the information to better characterize stars and their planets.


Jennifer van Saders

I'm currently a Carnegie-Princeton Postdoctoral Fellow at Carnegie Observatories, where I will be for another two years before moving to Princeton for 2 years. I got my B.S. from Rutgers University in astrophysics, and then went on to do my I did my PhD work at the Ohio State University on stellar evolution and structure. I've been working extensively with data from the Kepler space mission and stellar models to find new ways of learning about the states of stars.


"What's Up?" in this month will be presented by Chris Butler
