Confirming & detecting circumbinary planets using radial-velocities.

  • 1. University of Birmingham


Thanks to its long photometric stares, PLATO will likely identify multiple transiting circumbinary planets. However the duration of its long stares are insufficient to measure circumbinary planet masses accurately using eclipse timing variations of the central binary. In this talk I show our efforts on HARPS and SOPHIE to detect circumbinary planets orbiting single-lined eclipse binaries. I will show the first ground-based detections of circumbinary planets made by SOPHIE, HARPS in radial-velocities, and the
first circumbinary planet transit obtained from ground, using ASTEP in Antarctica. The methods we are developing are key to prepare for the confirmation of PLATO's circumbinary planets.
