ExcitH3+ is a code that computes the excitation of an H3+ molecule in astrophysical conditions.

ExcitH3+ - version from Felix-Gonzalez et al. (2024)

This version is the latest version of the 0D excitation code ExcitH3+, as used in Felix-Gonzalez et al. (2024). It includes new collisional (de)excitation rates with H. As shown in the paper, using scaled para-H2 rate coefficients as a proxy for H collision rates is not a good approximation. So, this updated version of ExcitH3p is the one to use to benefit from the new collision rates.

ExcitH3+ - version from Le Bourlot et al. (2023)

Logo

This is the code that is used in Le Bourlot et al. (2023), Molecular Physics, to explain the temperature of H3+ in diffuse clouds. As explained in the article, the originality of the method is to consider radiative and collisional processes as well as the chemical formation and destruction rates in the quantum states.
