Exploring the surface of HD 189733 via Doppler shadow analysis of planetary transits
E. C. Gonçalves, E. Cristo, W. Dethier +6
Transmission spectroscopy has greatly advanced the study of exoplanet atmospheres, but stellar surface heterogeneities can contaminate transit spectra. Characterising how stellar s…
Measuring Sub-Kelvin Variations in Stellar Temperature with High-Resolution Spectroscopy
Étienne Artigau, Charles Cadieux, Neil J. Cook +11
The detection of stellar variability often relies on the measurement of selected activity indicators such as coronal emission lines and non-thermal emissions. On the flip side, the…
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…
