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…

No statistically significant evidence for a correlation between stellar and planetary composition

Daisy A. Turner, Annelies Mortier, James G. Rogers +4

The chemical compositions of planets and their hosts stars are intrinsically linked, having formed from the same protostellar material. Characterising this relationship provides ke…

NGTS-39 b: A 58 d transiting warm Jupiter in an eccentric orbit

Ioannis Apergis, Daniel Bayliss, Solène Ulmer-Moll +53

We report the discovery and characterisation of NGTS-39 b (TIC 453147896 b), a warm Jupiter transiting a Sun-like star on a 58.2 day, eccentric (e = 0.386 +/- 0.019) orbit. NGTS-39…

Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system

H. Chakraborty, M. Lendl, A. Nigioni +27

HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…

Escape of Water- and Metal-enriched Atmospheres from compact Hot mini-Neptunes with CHAIN

Daria Kubyshkina, Jo Ann Egger, Caroline Piaulet-Ghorayeb

Recent observations reveal that atmospheric compositions of close-in sub-Neptunes are diverse and can differ strongly from pure H/He-dominated. We assess the possibility of modelli…

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…

Machine Learning as a Transformative Tool for (Exo-)Planetary Science

J. Davoult, V. T. Bickel, C. Haslebacher +11

The exploration of planetary bodies in our Solar system and beyond relies on the processing and interpretation of large, spatio-temporally inconsistent, and heterogeneous datasets.…

Constraining Small Planet Compositions for Future Missions

Larissa Palethorpe, Annelies Mortier, Jo Ann Egger +14

Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability. We present a uni…

Gas-depleted planet formation occurred in the four-planet system around the red dwarf LHS 1903

Thomas G. Wilson, Anna M. Simpson, Andrew Collier Cameron +173

Small exoplanet radii show two populations, referred to as super-Earths and sub-Neptunes, separated by a gap known as the radius valley. This may be produced by the removal of atmo…

Discovery and characterisation of two exoplanets orbiting the metal-poor, solar-type star TOI-5788 with TESS, CHEOPS, and HARPS-N

Ben S. Lakeland, A. Mortier, R. D. Haywood +48

We present the discovery and characterisation of two transiting exoplanets orbiting the metal-poor, solar-type star TOI-5788. From our analysis of six \textit{TESS} sectors and a d…
