Low-temperature Rosseland mean opacities on demand
See the paper Marigo & Aringer (2009) for code details, and Marigo et al. (2022) for the latest novelties. The former AESOPUS 1.0 interface is here. Note added on 14.02.2023: The accuracy of the EoS solution has been improved, and there may be minor changes (a few 0.001 dex) in the logarithm of Rosseland mean opacity compared to the previous version.
