Characterization of the atmosphere of the exoplanet Wasp-107b using SYSREM and cross-correlation

Sammanfattning

This project consists on the characterisation of the atmosphere of the exoplanet Wasp-107b, by observing the existence (or absence) of 4 different molecules: H20, CO2, CO and CH4. To achieve this we use 2 algorithms: - SYSREM, which eliminates the undesired stellar and thelluric features. -Cross-correlation, which compares the planetary spectrum with the molecules one. After applying these algorithms to 3 sets of simulations we can tell what mollecules are present in the planet's atmosphere.
