The Hubble WFC3 Emission Spectrum of the Extremely-Hot Jupiter, KELT-9b

no code implementations2 Jan 2021 Quentin Changeat, Billy Edwards

Aware of potential biases when combining instruments, we also analysed the HST spectrum alone and found that TiO and VO only were needed in this case.

Tracing the formation history of giant planets in protoplanetary disks with Carbon, Oxygen, Nitrogen and Sulphur

no code implementations28 Dec 2020 Diego Turrini, Eugenio Schisano, Sergio Fonte, Sergio Molinari, Romolo Politi, Davide Fedele, Olja Panic, Mihkel Kama, Quentin Changeat, Giovanna Tinetti

The S/N ratio provides an additional independent probe into the metallicity of giant planets and their accretion of solids.

Peeking inside the Black Box: Interpreting Deep Learning Models for Exoplanet Atmospheric Retrievals

1 code implementation23 Nov 2020 Kai Hou Yip, Quentin Changeat, Nikolaos Nikolaou, Mario Morvan, Billy Edwards, Ingo P. Waldmann, Giovanna Tinetti

We then present an extensive analysis of the predictions of DNNs, which can inform us - among other things - of the credibility limits for atmospheric parameters for a given instrument and model.
