A standard grid of templates and masks

Due to the very high atmospheric temperatures, their chemical composition is dominated by atoms and ions instead of molecules, while the formation of aerosols on their day-sides is unlikely. Thus, these planets offer the potential of detailed chemical characterisation by directly detecting elements through high-resolution day-side and transit spectroscopy.

This allows, in principle, to directly infer the element abundances of these objects, which may provide crucial constraints on their formation process and evolution history. In the recent past, several chemical species, mostly in the form of atoms and ions, have already been detected using high-resolution spectroscopy in combination with the cross-correlation technique. As part of the Mantis network, we provide a grid of standard templates in this study, designed to be used together with the cross-correlation method.
