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…
Binding energy distributions of alcohols, thiols, and their precursors on interstellar water ice surfaces
Arghyadeb Roy, Ankan Das, Milan Sil +4
Binding energy (BE) is a critical parameter in astrochemical modeling, governing the retention of species on interstellar dust grains and their subsequent chemical evolution. Howev…
Metallic species in interstellar medium: Astrochemical modeling
Ankan Das, Milan Sil, Paola Caselli
Metal-bearing species in diffuse or molecular clouds are often overlooked in astrochemical modeling except for the charge exchange process. However, catalytic cycles involving thes…
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…
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…
