A 43 day transiting Neptune and two 25 day Saturns from TESS, NGTS and ASTEP Open
Beyond orbital periods of 10 days, there is a dearth of known transiting gas giants. On longer orbits, planets are less affected by their host star, and become ideal probes of planet formation, migration and evolution. We report the discov…
