MENDOZA, S.; CANTO, J. e RAGA, A. C.. Hydrodynamical interaction between an accretion flow and a stellar wind. Rev. mex. astron. astrofis [online]. 2004, vol.40, n.2, pp.147-165. ISSN 0185-1101.
Molecular clouds in the interstellar medium suffer gravitational instabilities that lead to the formation of one or multiple stars. A recently formed star inside a cold cloud communicates its gravitational force to the surrounding environment and soon an accretion flow falling into the star develops. After their formation, all stars soon eject a wind of gas that interacts with the external accretion flow. This interaction produces a shock wave that evolves with time. The work presented in this article formulates a simple prescription for the evolution of this interaction. With the aid of this model we construct a few radio continuum maps of the source.
