Using Doppler Tomography for the Characterisation of Exoplanet Atmospheres

High resolution Doppler spectroscopy allows for the detection of molecules within the atmospheres of both transiting and non-transiting exoplanets, even when the planetary signal is buried beneath noise. Traditionally, this signal is extracted by cross-correlating model atmospheric spectra with the data. We have developed a new technique for probing exoplanet atmospheres ...
