Evidence for a giant companion orbiting Tabby's star

Cristina Madurga-Favieres, P. A. Strøm, Thomas G. Wilson +2

KIC 8462852, also known as Tabby's star, shows deep, irregular flux variations up to 20 per cent in its Kepler light curve. These unusual events show no apparent periodicity. Multi…

A Swarm of WASP Planets: Nine giant planets identified by the WASP survey

Nicole Schanche, Guillaume Hébrard, Keivan G. Stassun +52

The Wide Angle Search for Planets (WASP) survey provided some of the first transiting hot Jupiter candidates. With the addition of the Transiting Exoplanet Survey Satellite (TESS),…

Discovery of a cold giant planet and mass measurement of a hot super-Earth in the multi-planetary system WASP-132

N. Grieves, F. Bouchy, D. J. Armstrong +25

Hot Jupiters generally do not have nearby planet companions, as they may have cleared out other planets during their inward migration from more distant orbits. This gives evidence…

The NCORES Program: Precise planetary masses, null results, and insight into the planet mass distribution near the radius gap

David J. Armstrong, Ares Osborn, Remo Burn +39

NCORES was a large observing program on the ESO HARPS spectrograph, dedicated to measuring the masses of Neptune-like and smaller transiting planets discovered by the TESS satellit…

Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS

N. Heidari, G. H'ebrard, E. Martioli +65

We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…

Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396

A. Bonfanti, I. Amateis, D. Gandolfi +38

TOI-396 is an F6V star () orbited by three transiting planets. The orbital periods of the two innermost planets are close to the 5:3 commensurability ( d…
