Scientific paper

The chemistry in a mass-loaded T-Tauri wind-blown bubble is investigated. The basic dynamical character of the bubble and the general importance of the dynamics for the chemistry are described. The suggestion that H(+) and He(+) formed in the bubble are important in that chemistry is investigated. The model of the chemistry in the shock at the back of the shell and in the swept-up shell itself is summarized, and the results of the model calculations are presented. The relevance of the results to various observations is addressed, and it is speculated that the CO to H2 ratio in a cloud is a function of the activity in it. The chemical model developed here is applicable to regions in which multiple low-mass star formation is occurring.
