New Avenues in Atmospheric Modelling of Exoplanets
… been seen on the dayside atmospheres of some hot Jupiters and have been predicted to be caused by TiO or VO due to their visible opacity. I used the GENESIS model to investigate the effect of visible opacity and deduced that many new species (AlO, CaO, NaH and MgH), hitherto unexplored, are …

Towards Generalized Characterization of Exoplanet Atmospheres with Transit Spectroscopy
… spans a wide range of parameter space; from ultra-hot Jupiters with atmospheric temperatures beyond 3000 K, to temperate mini Neptunes that may host water in their atmospheres. Upcoming observational facilities in the next two decades will deliver exquisite spectra of exoplanet atmospheres at …

High resolution Doppler spectroscopy of a transiting ultra-hot Jupiter at optical wavelengths
… the huge, high-temperature exoplanets known as hot Jupiters are fascinating laboratories for extreme atmospheric physics, and their size, translucent atmospheres and proximity to their host stars makes them excellent targets for characterisation through transmission spectroscopy. Recently, …

Probing the atmospheres of transiting exoplanets using ground-based multi-object spectroscopy
… I present ground-based observations of three hot Jupiters which I modelled using Gaussian processes, a technique which allows me to robustly disentangle the planetary signals from the systematic noise. In addition, I introduce Student’s-T processes for exoplanet time-series, which are a …

Characterization of exoplanetary systems combining transit timing techniques and radial velocities: From secular perturbations to resonant chains
… I first explored tidal orbital decay in ultra-hot Jupiters through the analysis of WASP-12 b, using 12 years of ground-based photometry to confirm its decreasing orbital period while revealing intriguing discrepancies that challenge our understanding of stellar evolution and tidal …

Characterising Exoplanet Atmospheres with High-Resolution Transmission Spectroscopy
… detections in the transmission spectrum of a hot Jupiter. Next, I explore the diversity of ten highly irradiated giant exoplanets with equilibrium temperatures ranging from around 1000 to 4000 K. I conduct a homogeneous survey of sodium absorption using high-resolution transmission spectra …
