Opacities for atoms and molecules relevant to the spectra of hot rocky planets

This dataset contains opacities for atoms and molecules that are relevant to the sector of hot rocky planets, such as magma ocean planets, post-giant impact atmospheres, or planets in ultra-short period orbits. These species can arise above a magma ocean with a composition specific to the continental crust or bulk silicate earth. We do not include opacities for major species that are not specific to hot rocky planet atmospheres, such as water, methane, carbon dioxide, ammonia, etc., as these can be found elsewhere, for example in datasets related to brown dwarf and hot Jupiter atmospheres. Most of the species included in this dataset can be seen in the attached plot, hot_spectra.pdf, which shows a secondary eclipse model of a lava planet and the contributions of individual species to this spectrum. The references for the line lists used to generate these opacities can be found in the file reference_table.pdf. Each *.zip file contains a set of 1060 opacity layers in ASCII format, each identified with the temperature and pressure it corresponds to. Each layer file contains a header showing the layer number, the temperature (in K), and pressure (in mbar). The data consists of to columns: wavelength in microns and opacity in cm2/molecule. The wavelength grid goes from 0.4 to 50 microns. A list of all the layers calculated for each molecule is given in the file layer_list.
