Excited to share the latest paper from our Exoplanet Timeseries Characterisation (ExoTiC) team here at Bristol, this time led by (then MSc now PhD student) Charlotte Fairman 🥳 on The Importance of Optical Wavelength Data on Atmospheric Retrievals of Exoplanet Transmission Spectra from Hubble

Exoplanet transmission spectra provide rich information about the chemical composition, clouds and temperature structure of exoplanet atmospheres. Most exoplanet transmission spectra only span...

We took 14 #exoplanet@distantworlds.space ) to ask the question: "what information do I gain as I add in more optical data?" to demonstrate the need for @NASAHubble UV/optical measurements

14 planetary transmission (absorption) spectra with three model fits. Orange - just considering data longword of 1.1 microns. Blue considering  data long of 0.6 microns. Purple considering data long of 0.3 microns. With added data tighter constraints on the model can be seen.
