The EBLM Project XI. Mass, radius and effective temperature measurements for 23 M-dwarf companions to solar-type stars observed with CHEOPS

M. I. Swayne, P. F. L. Maxted, A. H. M. J. Triaud +104

Observations of low-mass stars have frequently shown a disagreement between observed stellar radii and radii predicted by theoretical stellar structure models. This ``radius inflat…

Characterising TOI-732 b and c: New insights into the M-dwarf radius and density valley

A. Bonfanti, M. Brady, T. G. Wilson +88

TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. By doubling the number of available space-based observations a…

Confirmation of TiO absorption and tentative detection of MgH and CrH in the atmosphere of HAT-P-41b

C. Jiang, G. Chen, F. Murgas +3

Understanding the role of optical absorbers is critical for linking the properties of the day-side and terminator atmospheres of hot Jupiters. This study aims to identify the signa…

No random transits in CHEOPS observations of HD 139139

R. Alonso, S. Hoyer, M. Deleuil +78

HD 139139 (a.k.a. 'The Random Transiter') is a star that exhibited enigmatic transit-like features with no apparent periodicity in K2 data. The shallow depth of the events (2…

Constraining the reflective properties of WASP-178b using Cheops photometry

I. Pagano, G. Scandariato, V. Singh +79

Multiwavelength photometry of the secondary eclipses of extrasolar planets is able to disentangle the reflected and thermally emitted light radiated from the planetary dayside. Thi…

Two mini-Neptunes Transiting the Adolescent K-star HIP 113103 Confirmed with TESS and CHEOPS

Nataliea Lowson, George Zhou, Chelsea X. Huang +31

We report the discovery of two mini-Neptunes in near 2:1 resonance orbits ( d for HIP 113103 b and d for HIP 113103 c) around the adolescent K-star HIP 11…
