Detection and characterisation of a 106-day transiting Jupiter: TOI-2449 b/NGTS-36 b

Soléne Ulmer-Moll, Samuel Gill, R. Brahm, Alastair B Claringbold et autres

Context . Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects, as their radius and mass can be measured and lead to an in-depth characterisation of the planet’s properties. …

Detection and characterisation of a 106-day transiting Jupiter : TOI-2449 b / NGTS-36 b

Soléne Ulmer-Moll, Samuel Gill, R. Brahm, Alastair B Claringbold et autres

Only a handful of transiting giant exoplanets with orbital periods longer than 100 days are known. These warm exoplanets are valuable objects as their radius and mass can be measured leading to an in-depth characterisation of the planet's properties. Thanks to low …

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 …

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 two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we cannot determine which star they orbit. The planets have radii of 1.00+/-0.11 R_Earth (TOI-2267 b, P=2.28 …

TESS discovery of a super-earth and three sub-neptunes hosted by the bright, sunlike star HD 108236

C.E. Henze, L.G. Bouma, M. Badenas-Agusti, S. Seager et autres

We report the discovery and validation of four extrasolar planets hosted by the nearby, bright, Sun-like (G3V) star HD 108236 using data from the Transiting Exoplanet Survey Satellite (TESS). We present transit photometry, reconnaissance, and precise Doppler spectroscopy, as well as high-resolution …

TOI-1136 is a Young, Coplanar, Aligned Planetary System in a Pristine Resonant Chain

Fei Dai, K. Masuda, Corey Beard, Paul Robertson et autres

Convergent disk migration has long been suspected to be responsible for forming planetary systems with a chain of mean-motion resonances (MMR). Dynamical evolution over time could disrupt the delicate resonant configuration. We present TOI-1136, a 700-Myr-old G star hosting at least 6 …
