A CHEOPS-enhanced view of the HD3167 system

V. Bourrier, A. Deline, A. Krenn +92

Much remains to be understood about the nature of exoplanets smaller than Neptune, most of which have been discovered in compact multi-planet systems. With its inner ultra-short pe…

The phase curve and the geometric albedo of WASP-43b measured with CHEOPS, TESS and HST WFC3/UVIS

G. Scandariato, V. Singh, D. Kitzmann +79

Observations of the phase curves and secondary eclipses of extrasolar planets provide a window on the composition and thermal structure of the planetary atmospheres. For example, t…

Two temperate super-Earths transiting a nearby late-type M dwarf

L. Delrez, C. A. Murray, F. J. Pozuelos +82

In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their atmospheres, as well as searching fo…

The stable climate of KELT-9b

K. D. Jones, B. M. Morris, B. -O. Demory +76

Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as the hottest planet thus far discovered with a dayside temperature of over 4500K. At t…

The HD 93963 A transiting system: A 1.04d super-Earth and a 3.65 d sub-Neptune discovered by TESS and CHEOPS

L. M. Serrano, D. Gandolfi, S. Hoyer +109

We present the discovery of two small planets transiting HD 93963A (TOI-1797), a G0\,V star (M=1.109\,\,0.043\,M, R=1.043\,\,0.009\,R) in a visual…

Uncovering the true periods of the young sub-Neptunes orbiting TOI-2076

Hugh P. Osborn, Andrea Bonfanti, Davide Gandolfi +93

Context: TOI-2076 is a transiting three-planet system of sub-Neptunes orbiting a bright (G = 8.9 mag), young ( Myr) K-type star. Although a validated planetary system, th…

CHEOPS geometric albedo of the hot Jupiter HD 209458b

A. Brandeker, K. Heng, M. Lendl +74

We report the detection of the secondary eclipse of the hot Jupiter HD 209458b in optical/visible light using the CHEOPS space telescope. Our measurement of 20.4 +/- 3.3 ppm transl…

Investigating the architecture and internal structure of the TOI-561 system planets with CHEOPS, HARPS-N and TESS

G. Lacedelli, T. G. Wilson, L. Malavolta +115

We present a precise characterization of the TOI-561 planetary system obtained by combining previously published data with TESS and CHEOPS photometry, and a new set of HARPS-N…

A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS

Thomas G. Wilson, Elisa Goffo, Yann Alibert +132

We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise…

The atmosphere and architecture of WASP-189 b probed by its CHEOPS phase curve

A. Deline, M. J. Hooton, M. Lendl +83

Gas giants orbiting close to hot and massive early-type stars can reach dayside temperatures that are comparable to those of the coldest stars. These "ultra-hot Jupiters" have atmo…
