Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
S. Sulis, M. Lendl, H. Cegla +83
Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…
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…
A stellar occultation by the transneptunian object (50000) Quaoar observed by CHEOPS
B. E. Morgado, G. Bruno, A. R. Gomes-Júnior +82
Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on the photometric accuracy, the t…
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…
Ariel stellar characterisation: I -- homogeneous stellar parameters of 187 FGK planet host stars Description and validation of the method
L. Magrini, C. Danielski, D. Bossini +16
In 2020 the European Space Agency selected Ariel as the next mission to join the space fleet of observatories to study planets outside our Solar System. Ariel will be devoted to 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…
