Retrievals are modelling tools able to scrutinise the atmospheric transmission or emission spectra of planets, iteratively comparing these spectra with a parametrised radiative transfer model using Bayesian frameworks. To help illuminate the capabilities of a retrieval, I will be presenting the emission and reanalysed transmission spectra of WASP-79b, an inflated hot-Jupiter first detected by Smalley et al. 2012. WASP-79b has been explored in literature previously by Skas et al. 2020, Sotzen et al. 2020, Rathcke et al. 2021; all studies agreeing on detections of H2O with various confidence levels, with the latter finding moderate evidence of an H-bound free opacity compared to iron hydride (FeH) abundance found by other studies. Using the publicly available Iraclis data analysis pipeline and the retrieval framework TauREx 3, I will be adding to the global picture of this planet by examining the Hubble Space Telescope emission spectra as captured by the Wide Field Camera 3 G141 grism (PI: David Sing, proposal ID: 14767) and the Spitzer Space Telescope (Garhart et al. 2020). Further work on wrapping ATMO, a 1D atmospheric modelling tool developed by Pascal Tremblin, as a plug-in for TauREx, to further this retrieval tool’s abilities will also be explored, as well as comparisons to PARC, ATMO’s Python retrieval tool.
