The transmission spectrum of WASP-17 b from the optical to the near-infrared wavelengths: combining STIS, WFC3 and IRAC datasets
Arianna Saba, Angelos Tsiaras, Mario Morvan +6
We present the transmission spectrum of the inflated hot-Jupiter WASP-17 b, observed with the STIS and WFC3 instruments aboard the Hubble Space Telescope, allowing for a continuous…
Characterising a World Within the Hot Neptune Desert: Transit Observations of LTT 9779 b with HST WFC3
Billy Edwards, Quentin Changeat, Angelos Tsiaras +27
We present an atmospheric analysis of LTT 9779 b, a rare planet situated in the hot Neptune desert, that has been observed with HST WFC3 G102 and G141. The combined transmission sp…
A Population Analysis of 20 Exoplanets Observed from the Optical to the Near-infrared Wavelengths with HST: Evidence for Widespread Stellar Contamination
Arianna Saba, Alexandra Thompson, Kai Hou Yip +4
We present a population study of 20 exoplanets, ranging from Neptune-like to inflated hot-Jupiter planets, observed during transit with the STIS and WFC3 instruments aboard the Hub…
Correcting Exoplanet Transmission Spectra for Stellar Activity with an Optimised Retrieval Framework
Alexandra Thompson, Alfredo Biagini, Gianluca Cracchiolo +7
The chromatic contamination that arises from photospheric heterogeneities e.g. spots and faculae on the host star presents a significant noise source for exoplanet transmission spe…
