The WINE collaboration: a Warm Giants planets survey

Warm giants, planets broadly defined as planets orbiting their host star with periods longer than 10 days, remained elusive to ground-based transit searches, mainly due to the constrains imposed by the daily cycle. While some detections were possible with the Kepler+K2 missions, only with TESS it has been possible to systematically characterize them, either through the detection of periodic transiting signals or single transiters. By complementing transit observations with radial velocity (RV) measurements, it is possible to provide a detailed characterization of the dynamical properties of the planetary system.

The Warm gIaNts with TESS (WINE) collaboration is a dedicated survey to identify, confirm and characterize warm giants using TESS data and ground-based photometric and spectroscopic follow-up facilities, with the main goal of building a giant planets database to constrain theories of planetary formation and evolution. We have detected more than 20 Warm giants and we have been following up dozens of exoplanet candidates. In this talk I will provide an overview of the survey, highlighting the most relevant results of this project.

The seminar will be held in person but will be streamed online via Zoom: https://cesnet.zoom.us/j/95563860682?pwd=DGNZSanatDXzSpa2NAe8I9ybyR6ban.1
