Searching for hot water world candidates with CHEOPS: II. A low-density super-Earth orbiting the K dwarf TOI-2211

J. A. Egger, P. Cortés-Zuleta, D. Kubyshkina +98

Small exoplanets on close-in orbits are exposed to high levels of stellar irradiation, which can effectively remove low-mass primordial H/He envelopes through atmospheric escape. U…

JWST-SUPER I: New insights into irradiated warm Neptunes atmospheres from MIRI observations of HD 106315 c

A. Dyrek, R. Waters, S. -M. Tsai +17

Sulphur-bearing molecules have recently emerged as powerful tracers of atmospheric photochemistry in exoplanets observed with JWST. In several warm giant planets, SO has been d…

CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c

Z. Garai, Gy. M. Szabó, D. Gandolfi +90

We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…

CAFE follow-up of TESS hot Jupiter candidates left behind: I. Five newly confirmed planets and a false positive

J. Lillo-Box, C. Cifuentes, O. Balsalobre-Ruza +56

Hot Jupiters are key targets for understanding planet formation, migration, and atmospheres. Yet, most ground-based follow-up resources for the TESS mission are focused on confirmi…

Oxygen and nitrogen isotopologues on cold COCONUTS-2b observed with MIRI/MRS

H. Kühnle, E. C. Matthews, P. Mollière +12

Linking the composition of gas giant planets to their formation paths has long been a goal in exoplanet science. Especially, cold gas giants with temperatures below 500K have…

An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95

We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…

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…

Information content of JWST transmission spectroscopy of the exoplanet HAT-P-12b from the optical to the mid-infrared

L. Heinke, M. Min, J. Bouwman +18

The James Webb Space Telescope (JWST) provides low- to medium-resolution spectra with unprecedented precision and broad near- to mid-infrared wavelength coverage, enabling detailed…
