    "description": "<p>Thanks to its long photometric stares, PLATO will likely identify multiple&nbsp;transiting circumbinary planets. However the duration of its long stares are&nbsp;insufficient to measure circumbinary planet masses accurately using eclipse&nbsp;timing variations of the central binary. In this talk I show our efforts&nbsp;on HARPS and SOPHIE to detect circumbinary planets orbiting single-lined&nbsp;eclipse binaries. I will show the first ground-based detections of&nbsp;circumbinary planets made by SOPHIE, HARPS in radial-velocities, and the<br>\nfirst circumbinary planet transit obtained from ground, using ASTEP in&nbsp;Antarctica. The methods we are developing are key to prepare for the&nbsp;confirmation of PLATO&#39;s circumbinary planets.<br>\n<br>\n&nbsp;</p>",
