Minimizing Star Spot Contamination of Exoplanet Transit Spectroscopy Using Alternate Normalization
Recently, Currie et al. simulated the detection of molecules in the atmospheres of temperate rocky exoplanets transiting nearby M-dwarf stars. They simulated detections via spectral cross-correlation ...
