Title: Characterizing hot Jupiter atmospheres through high resolution eclipse spectroscopy

Presenter: Melissa Marquette


By combining analysis conducted using simplified toy models, full blown GCMs, and ultimately real data, we aim to explore the limits of what atmospheric conditions are detectable in the spectra of hot Jupiters. Given that multiple molecular species, including H2O and CO (Brogi et al. 2013), have already been robustly detected using high resolution spectroscopy (Birkby 2018), we seek to push these detections further by using high resolution spectra taken during secondary eclipses to infer how these spectral lines may have been altered by the conditions under which they were produced (e.g. their shape, depth) and use that to inform us about atmospheric characteristics. To do this, we combine simplified toy models that demonstrate the scale of the effects of atmospheric conditions on spectral lines with full blown GCMs capable of creating a more realistically complex portrait of what these effects might look like in the resulting spectra we observe. This will inform our target selection and observational strategy to conduct future observations using the new SPIRou spectopolarimeter on CFHT, as well as our ultimate handling of the data to enable us to extract as much information as possible.
