Resumo

The detection of exoplanet atmospheres is now possible thanks to the development of new instruments and data analysis methods. One of the promising avenues in this field is the use of the Rossiter-McLaughlin effect: an anomaly in the spectrum of a star caused by the passage of the planet in from of its disk, producing radial velocity variations. This anomaly depends on the radius of the planet (among other system parameters), and as such, variations in planet radii as a function of wavelength caused by different atmospheric dispersion processes will have an impact on the detected signal.
 
The goal of the present project is to explore the potential of the new ESPRESSO spectrograph (ESO, VLT) to detect exoplanet atmospheres using the Rossiter-McLauglin effect.
