Hydrodynamic simulations of molecular outflows driven by fast-precessing protostellar jets.
ROSEN A. and SMITH M.D.
Abstract (from CDS):
Images, position-velocity diagrams and channel maps for H2and CO transitions are analysed. Testable predictions are made for the upcoming generation of high-resolution submillimetre and far-infrared telescopes. The distributions of both mass and CO emission-line flux with radial velocity are predicted and compared to observations. A clear dependence of the slope of the mass-velocity (or luminosity-velocity) distribution on the precession angle is found, which may help us to interpret the variety of reported line profiles.
We compute the evolution of radiative emission relative to the mean jet power for these simulations and previous molecular jet simulations in this series. The H21-0 S(1) emission is roughly a factor of 0.001 of the mean power in the dense jets and 0.01 in the light jets, consistent with the kinetic energy of the light jets being more efficiently radiated.
