Description
Previous studies in the scope of Icy Giants entries and aerocapture have highlighted \cite{Coelho:2023} that small concentrations of \ce{CH4} in the freestream, as well as injection of carbon-containing ablation products in the boundary layer may yield dramatic increases of radiation, owing to the formation of C-containing species that are known to be strongly radiative at the representative post-shock temperatures.
In the scope of our analysis presented in our other conference paper (Radiative Heating for Ice Giant Entries), it is found that radiation from the \ce{C2} Deslandres-d'Azambuja radiative system is dominant, with radiation of the \ce{C2} Swan System a second to this system.
However, neither ground-test experiments, neither other studies in related thermodynamic conditions (radiation emitted from Brown Dwarf stars) show a preponderance of the \ce{C2} Deslandres-d'Azambuja system, compared to the \ce{C2} Swan System, with both Systems having at best euivalent intensities.
We have therefore re-investigated the Einstein coefficients for this system. Our findings will be presented in this work. We will conclude the presentation with a small outlook on a work of James Prescott Joule on Shooting Stars.
