Sonora 2018: Cloud-Free, Solar Composition, Solar C/O Substellar Evolution Models

Tables of the evolution of brown dwarfs and extrasolar planets based on the model described in Marley et al.(2019, in prep.). This publication provides a detailed description of the physics included in the model. The main differences with the previously published tables by Saumon & Marley (2008) are • updated "Sonora 2018" atmosphere models used as the surface boundary conditions, primarily involving improvements in the opacities of H2, CH4 and alkali resonance lines. The new atmosphere models are described in Marley et al. (2019, in prep.). • including metals in the interior equation of state as an additional amount of helium. Currently, the evolution tracks are for solar metallicity abundances ([M/H]=0) and solar C/O ratio (defined relative to solar, so C/O=1 here) with cloudless atmospheres. Please cite Marley et al. (2019, in prep.) if you use these in a publication.
