During my PhD, I have been using the HRS technique to analyze the spectra acquired with the high-resolution near-infrared (NIR) spectrograph GIANO mounted on the Telescopio Nazionale Galileo (TNG), La Palma, Spain. Despite the TNG is an only 3.6-m class telescope, during the first year of my PhD, we have demonstrated that it can be successfully employed to characterize the lower atmosphere of transiting exoplanets, i.e. planets that pass in front of the host stars as seen from the Earth;(Brogi, Giacobbe, Guilluy et al. 2018, A&A). For this work, I have developed a pipeline for the analysis of the GIANO spectra and I have applied it to investigate the atmospheric composition of the hot Jupiter HD189733b. During the second year of my PhD, I have then readapted my pipeline to characterize the atmosphere of a non-transiting planet (i.e. a planet which does not transit the host star as seen from Earth): the hot Jupiter HD 102195b (Guilluy et al 2019, A&A). I analyzed the GIANO spectra to characterize the spectrum directly emitted by the planet’s dayside and, from the comparison of the empirical spectra with theoretical models, I have detected water vapor and methane in its atmosphere with a 4.4 sigma and 4.1 sigma levels of statistical significance. This is the first detection of methane in a hot Jupiter with the HRS technique. Together with the search for molecules, during the second year of my PhD I have also characterized the upper atmosphere (thermosphere and exosphere) of exoplanets through the analysis of a new diagnostic for evaporation processes, the metastable helium triplet at 1083.3 nm. In particular, I have performed transmission spectroscopy on the GIANO-B (the recent upgrade of GIANO) spectra of the hot Jupiter HD 189733b, and I have detected a helium signal in its upper atmosphere. Now I am writing a paper as leading author about this study, and I am also trying to characterize possible stellar contaminations to the detected helium planetary signal. Finally, during the second year of my PhD, I also made an observing run of 8 night at the TNG, and I started a new collaboration with the Geneva University for the analysis of the GIANO-B spectra, this collaboration will lead to papers.
