CH3+ : a cornerstone of interstellar chemsitry. CH3+ : proposed to be a cornerstone of interstellar chemistry in the late 70’s Searched for by astronomers, but not detected => Alternative routes for chemistry Detection with JWST implies gas phase formation Two diagrams show a network of chemical reactions that are all centered around CH3+

   A neat interdisciplinary science story from Olivier Berne and the PDRs4All project.

   They saw this forrest of emission lines in their observations of the Orion Bar, a star forming region. After talking with some chemists, they found it was from the Methyl-Cation (CH3+).

   Chemists had been studying it for years, but didn't have a great spectrum. The JWST data is better than anything that could be measured on Earth. With the new data, they were able to make a much better model.
