ASTEP confirmation of a pair of long-period Jupiter-sized planets with extremely low densities transiting TOI-791

Georgina Dransfield, Antoine C. Petit, Amaury H. M. J. Triaud +45

Gas giant planets with periods orbiting Sun-like stars are a relatively uncommon outcome of planetary formation, and key questions about the nature and form…

The small transiting planet population revealed by ESPRESSO with extreme precision radial velocities

M. J. Hobson, B. Lavie, F. Bouchy +35

Small planets are extremely common in the Galaxy, including planets with masses and radii between those of Earth and Neptune. Characterizing these planets' masses requires ultra-pr…

The atmosphere of the warm Neptune GJ 436 b probed with ESPRESSO

E. Herrero-Cisneros, M. R. Zapatero Osorio, J. Sanz-Forcada +21

Aims. We aim to identify the presence of atomic and molecular species in the upper atmosphere of the warm Neptune-sized transiting planet GJ 436 b, which has a radiative equilibriu…

The multi-planet system TOI-5624: Four transiting sub-Neptunes with an outer companion revealed by transit-timing variations

A. Bonfanti, D. Gandolfi, P. Leonardi +96

Following the 2022 alert of a TESS object of interest transiting TOI-5624 (a G7 V star 100 pc away), a CHEOPS campaign in 2023 detected four planetary signals at $P_b\approx3…

Long-term outburst activity of comet 17P/Holmes and constraints on ejecta size distributions

Maria Gritsevich, Marcin Wesołowski, Josep M. Trigo-Rodríguez +4

A quantitative understanding of cometary outbursts requires robust constraints on the size distribution of ejected particles, which governs outburst dynamics and underpins estimate…
