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…

A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067

R. Luque, H. P. Osborn, A. Leleu +149

Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…

CHEOPS observations of KELT-20 b/MASCARA-2 b: An aligned orbit and signs of variability from a reflective dayside

V. Singh, G. Scandariato, A. M. S. Smith +87

Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information on the spin-orbit alignment…

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…

The limit of macroscopic homogeneous ice nucleation at the nanoscale

John A. Hayton, Michael B. Davies, Thomas F. Whale +2

Nucleation in small volumes of water has garnered renewed interest due to the relevance of pore condensation and freezing under conditions of low partial pressures of water, such a…

Refined parameters of the HD 22946 planetary system and the true orbital period of planet d

Z. Garai, H. P. Osborn, D. Gandolfi +85

Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…

TOI-5678 b: A 48-day transiting Neptune-mass planet characterized with CHEOPS and HARPS

S. Ulmer-Moll, H. P. Osborn, A. Tuson +92

A large sample of long-period giant planets has been discovered thanks to long-term radial velocity surveys, but only a few dozen of these planets have a precise radius measurement…

How Crystalline is Low-Density Amorphous Ice?

Michael Benedict Davies, Alexander Rosu-Finsen, Christoph G. Salzmann +1

Low-density amorphous ice (LDA) is one of the most common solid materials in the Universe and a key material for understanding the many famous anomalies of liquid water. Yet, despi…

A new dynamical modeling of the WASP-47 system with CHEOPS observations

V. Nascimbeni, L. Borsato, T. Zingales +80

Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple planetary systems, the archi…

TOI-1055 b: Neptunian planet characterised with HARPS, TESS, and CHEOPS

A. Bonfanti, D. Gandolfi, J. A. Egger +89

TOI-1055 is a Sun-like star known to host a transiting Neptune-sized planet on a 17.5-day orbit (TOI-1055 b). Radial velocity (RV) analyses carried out by two independent groups us…

A full transit of Lupi d and the search for an exomoon in its Hill sphere with CHEOPS

D. Ehrenreich, L. Delrez, B. Akinsanmi +90

The planetary system around the naked-eye star Lupi (HD 136352; TOI-2011) is composed of three exoplanets with masses of 4.7, 11.2, and 8.6 Earth masses. The TESS and CHEOPS…
