Outline The Kepler Mission Eccentric binary systems Heartbeat stars Our results The future

The Kepler Satellite Launched in 2009 Looking for variability in over 145,000 stars 122 planets confirmed 2740 planetary candidates 2165 eclipsing binary systems

Eccentric Binary Systems

Tidally Induced Distortions

Heartbeat Stars Eccentric binaries with dynamic tidal distortions

Observations 11 nights of data over six months 4 stars observed:  KIC  KIC  KIC  KIC

KIC A4 Star Temperature: 8750 K Period: days Eccentricity: 0.588

The Sodium Mystery

KIC F3 Star Temperature: 6750 K Period: days Eccentricity: 0.423

KIC A9 Star Temperature: 7750 K Period: days Eccentricity: 0.600

KIC F3 Star Temperature: 6750 K Period: days Eccentricity: 0.618

The Future We will continue observing these targets and add more to our sample This should allow us to determine some of the unique characteristics of the system  Better understand distortions and pulsations We may also be better able to predict the formation scenarios for this type of system We will better understand stellar evolution
