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…

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…

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…
