Abstract

The paper presents an analytical theory for propagation of induced star formation. The model takes into consideration a nonlocal influence in the interactions of gas clouds and stellar systems and time-delay processes in formation of new stars in clouds which have experienced the influence of previous generations of stars. The analytical solutions for propagating waves of star formation are obtained. Numerical simulations of basic equations demonstrate the formation of stationary waves and confirm the analytical results.

In two-dimensional case the formation of circular propagating waves of star formation is demonstrated. These structures can be associated with observed rings of enhanced star formation (Appleton and Struck-Marcel, 1987).
