TOI-7510: A solar-analog system of three transiting giant planets near a Laplace resonance chain

J. M. Almenara, A. Leleu, T. Guillot, R. Mardling et autres

We report the confirmation and initial characterization of a compact and dynamically rich multiple giant planet system orbiting the solar analog TOI-7510. The system was recently identified as a candidate two-planet system in a machine-learning search of the TESS light curves. Using …

Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267

Sebastián Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares, N. Cuello et autres

We report the discovery of two warm exoplanets orbiting the cool binary system TOI-2267, composed of the M5 (TOI-2267A) and M6 (TOI-2267B) stars, whose angular separation is 0.384 arcsec, corresponding to a projected distance of only about 8 au at 22 pc …

Architecture of TOI-561 planetary system

G. Piotto, T. Zingales, L. Borsato, J. A. Egger et autres

We present new observations from CHEOPS and TESS to clarify the architecture of the planetary system hosted by the old Galactic thick disk star TOI-561. Our global analysis, which also includes previously published photometric and radial velocity data, incontrovertibly proves that TOI-561 …

A remnant planetary core in the hot-Neptune desert

T.-G. Tan, R.A. Booth, A. Osborn, P. J. Wheatley et autres

The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of planetary cores. Exoplanets that have undergone rare evolutionary processes provide a route to understanding planetary …

Three short-period Jupiters from TESS: HIP 65Ab, TOI-157b, and TOI-169b

A. Jordán, L.A. Dos Santos, P. Eigmüller, D. Ségransan et autres

We report the confirmation and mass determination of three hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS) mission: HIP 65Ab (TOI-129, TIC-201248411) is an ultra-short-period Jupiter orbiting a bright (V = 11.1 mag) K4-dwarf every 0.98 days. It is a …

Six newly-discovered hot Jupiters transiting F/G stars: WASP-87b, WASP-108b, WASP-109b, WASP-110b, WASP-111b & WASP-112b

D. R. Anderson, D. J. A. Brown, A. Collier Cameron, L. Delrez et autres

We present the discoveries of six transiting hot Jupiters: WASP-87b, WASP-108b, WASP-109b, WASP-110b, WASP-111b and WASP-112b. The planets have masses of 0.51--2.2 $M_{\rm Jup}$ and radii of 1.19--1.44 $R_{\rm Jup}$ and are in orbits of 1.68--3.78 d around stars with masses 0.81--1.50 …
