C, N, O, S, and photochemistry in a temperate giant planet orbiting a late M dwarf
Michael Zhang, Qiao Xue, Jeehyun Yang +20
We report the JWST NIRSpec/PRISM transit spectrum of TOI-6894b, an exceptional 420 K sub-Saturn that is one of the rare giant planets transiting a late M dwarf. Remarkably, both th…
The Wonderful World of Binary Stars
Andrea Barone, Henri M. J. Boffin, Beatrice Caccherano +6
During the 2026 ESO La Silla Observing school, about twenty students attended lectures and performed observations to learn various aspects of observational astronomy. The school, w…
A Cold and Super-Puffy Planet on a Prograde Orbit
Juan I. Espinoza-Retamal, Rafael Brahm, Cristobal Petrovich +36
We report the discovery of TOI-4507 b, a transiting sub-Saturn with a density 0.2 g/cm on a 105-day prograde orbit around a 700 Myr old F star. The transits were detected u…
Ten Aligned Orbits: Planet Migration in the Era of JWST and Ariel
J. Zak, H. M. J. Boffin, A. Bocchieri +3
Understanding the diverse formation and migration pathways that shape exoplanetary systems requires characterizing both their atmospheric properties and their orbital dynamics. A k…
Stellar obliquities of eight close-in gas giant exoplanets
J. Zak, H. M. J. Boffin, E. Sedaghati +4
The Rossiter-McLaughlin effect allows us to measure the projected stellar obliquity of exoplanets. From the spin-orbit alignment, planet formation and migration theories can be tes…
Detection of faculae in the transit and transmission spectrum of WASP-69b
D. J. M. Petit dit de la Roche, H. Chakraborty, M. Lendl +9
Context: Transmission spectroscopy is a powerful tool for understanding exoplanet atmospheres. At optical wavelengths, it makes it possible to infer the composition and the presenc…
HD 110067 c has an aligned orbit
J. Zak, H. M. J. Boffin, E. Sedaghati +25
Planetary systems in mean motion resonances hold a special place among the planetary population. They allow us to study planet formation in great detail as dissipative processes ar…
Stellar obliquity measurements of six gas giants
J. Zak, A. Bocchieri, E. Sedaghati +11
One can infer the orbital alignment of exoplanets with respect to the spin of their host stars using the Rossiter-McLaughlin effect, thereby giving us the chance to test planet for…
