New Bistable Solutions in Molecular Cloud Chemistry: Nitrogen and Carbon Autocatalysis
Dufour Gwenaëlle, Steven B. Charnley
We have investigated the chemistry of dense interstellar clouds and found new bistable solutions in the nitrogen and carbon chemistries. We identify the autocatalytic processes tha…
Oscillations in Gas-grain Astrochemical Kinetics
Gwenaëlle Dufour, Steven B. Charnley, Johan E. Lindberg
We have studied gas-grain chemical models of interstellar clouds to search for nonlinear dynamical evolution. A prescription is given for producing oscillatory solutions when a bis…
Astrochemical Bistability: Autocatalysis in Oxygen Chemistry
G. Dufour, S. B. Charnley
The origin of bistable solutions in the kinetic equations describing the chemistry of dense interstellar clouds is explained as being due to the autocatalysis and feedback of oxyge…
A new study of the chemical structure of the Horsehead nebula: the influence of grain-surface chemistry
Romane Le Gal, Eric Herbst, Gwenaelle Dufour +4
A wide variety of molecules have recently been detected in the Horsehead nebula photodissociation region (PDR) suggesting that: (i) gas-phase and grain chemistries should both cont…
