Title: Interaction of Protostellar Winds with the Orion Molecular Cloud
Abstract: The effect of a strong protostellar wind on a dense molecular cloud with a magnetic field is investigated by time-dependent magnetohydrodynamic calculations which take into account the cooling due to H 2 molecules as the dominant one. The shocked region obtained here seems to be responsible for the formation of the bright H 2 emission with a high-velocity width observed in the Orion-KL Nebula.
