A Kepler Transiting Circumbinary Planet
摘要:
Among the thousands of planet candidates discovered by Kepler only a few have been detected in binary star systems. To date, seven transiting circumbinary planets have been confirmed, with several more candidates planets under investigation. Of the confirmed cases, the planets orbit short-period eclipsing binaries that have periods between one and seven weeks. The eclipsing binary nature of the stars allows their masses and radii to be accurately determined. Perturbations of the binary can be detected by eclipsing timing variations, sometimes allowing the mass of the planet to be measured. In this talk, we present the most recent Kepler transiting circumbinary planet. We gratefully acknowledge support from the NSF via grant AST-1109928, and from NASA via Kepler PSP grant NNX12AS23G and OSS grant NNX12AI76G.
