KESPRINT: From warm Jupiters to rocky ultra-short period planets

Kurzfassung

Radial velocity observations, coupled with precise photometry, of bright stars hosting transiting planets allow the determination of planetary densities. These provide vital constraints for studies of planetary composition and formation. The KESPRINT consortium has provided more than one third of the mass measurements of planets discovered by K2. Our discoveries range from warm Jupiters to systems with multiple short-period rocky planets. The combination of TESS photometry with ground-based telescopes equipped with spectrographs is proving invaluable in determining planetary densities for planets transiting bright stars, which make excellent targets for future characterisation efforts. This poster provides a summary of recent KESPRINT work on the detection and characterisation of exoplanetary systems discovered by both K2 and TESS. We also place these results into context, showing how they contribute to our understanding of planet diversity.
