Scientific paper

We have shown recently that models of interstellar chemistry could exhibit several stable steady-states. Here, we investigate in more detail the influence of various astrophysical parameters that control the evolution and the final state of the gas such as the density, cosmic ray ionization rate and elemental depletions. The temperature is computed from the thermal balance equation. We show that, within the frame of our chemical network, these parameters lead to bistability for a range of physical conditions appropriate to interstellar clouds. The degree of ionization is the key variable that distinguishes the different solutions. Both steady state and evolution aspects are discussed. One case of chemical oscillations is also reported.
