Separating planetary reflex Doppler shifts from stellar variability in the wavelength domain
A. Collier Cameron, E. B. Ford, S. Shahaf +28
Stellar magnetic activity produces time-varying distortions in the photospheric line profiles of solar-type stars. These lead to systematic errors in high-precision radial-velocity…
WASP-127b: A misaligned planet with a partly cloudy atmosphere and tenuous sodium signature seen by ESPRESSO
R. Allart, L. Pino, C. Lovis +45
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. The transmission spectroscopy technique is playing a significa…
Three Years of HARPS-N High-Resolution Spectroscopy and Precise Radial Velocity Data for the Sun
X. Dumusque, M. Cretignier, D. Sosnowska +35
The solar telescope connected to HARPS-N has been observing the Sun since the summer of 2015. Such high-cadence, long-baseline data set is crucial for understanding spurious radial…
RASSINE: Interactive tool for normalising stellar spectra I. Description and performance of the code
Michael Cretignier, Jérémie Francfort, Xavier Dumusque +2
Aims: We provide an open-source code allowing an easy, intuitive, and robust normalisation of spectra. Methods: We developed RASSINE, a Python code for normalising merged 1D spectr…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) III. Atmospheric structure of the misaligned ultra-hot Jupiter WASP-121b
V. Bourrier, D. Ehrenreich, M. Lendl +21
Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present…
