Rebecca Webb


I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick under the supervision of Dr Matteo Brogi.


My project looks into characterising extra-solar (exoplanet) atmospheres using the high-resolution cross-correlation spectroscopy method (HRCCS). By observing the thermal, day-side emission of the planet in incredibly fine detail (R = $\frac{\lambda}{\Delta\lambda}$ ~ 100,000), we can robustly detect the chemical make-up and subsequently the physical processes of the planet. Because of the inherintly faint signal from the planet, we have to use some of the biggest telescopes (e.g. the VLT) with some of the most stable spectrographs (e.g. CARMENES, mounted on the Calar Alto Observatory) in the world to detect the orbital signature from the planet. My project focusses primarily on characterising non-transiting hot Jupiters which predominantly have favourable observing conditions due to their higher contrasts in the near-infrared (NIR) compared to their host stars.
