Descrição
Resumo:Molecular clouds in the interstellar medium suffer gravitational instabilitiesthat lead to the formation of one or multiple stars. A recently formed star insidea cold cloud communicates its gravitational force to the surrounding environmentand soon an accretion flow falling into the star develops. After their formation, allstars soon eject a wind of gas that interacts with the external accretion flow. Thisinteraction produces a shock wave that evolves with time. The work presented inthis 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.
