Chemistry and ro-vibrational excitation of CH in the planetary nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
Small carbon hydride cations, such as the methylidyne ion (CH), play an important role in the chemistry of the interstellar medium (ISM). They participate in gas-phase reaction…
Chemistry and ro-vibrational excitation of HeH in the Planetary Nebula NGC 7027
Milan Sil, Alexandre Faure, Helmut Wiesemeyer +5
HeH belongs to the class of "reactive" ions that can be destroyed so quickly that chemical formation and destruction rates may compete with inelastic rates and should be consid…
Dissociative recombination of NH: Isotopic effects
J. Zs. Mezei, A. Orban, S. Demes +4
The investigation of the isotopic ratio of interstellar nitrogen -- N versus N -- is done, for explaining its variations observed for N2H+ in different interstellar a…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
