Title:Molecular Line Lists For Hot Rocky Super-earths
Author(s):Owens, Alec

Subject(s):Linelists
Abstract:The atmospheres of hot rocky super-Earths will have very different spectroscopic signatures compared to gas giants or cooler objects. Many of these exoplanets possess short orbital periods, hence hot atmospheres, and will have a lot in common with early Earth; the massive amounts of water and elevated temperatures are expected to turn the atmospheres into a (high pressure) steam bath containing the remains of melted rock.\\ We will present recent progress on the production of molecular line lists for hot rocky super-Earths. A number of molecules containing silicon, alkali and alkaline earth metals are to be included in the ExoMol database. For the temperature and wavelength ranges considered, line lists will have to come from rigorous, first-principles calculations. However, these species pose new challenges and there is a pressing need for laboratory observations to improve the accuracy of our spectroscopic models.
