We analyze the structure and stability of the transition lay er (or front) that connects the cold neutral medium and warm neutral medium in the planeparallel geometry. Such fronts appear in recent numerical simulations of a ther mally bistable interstellar medium. The front becomes an evaporation or condensatio n front depending on the surrounding pressure… CONTINUE READING
