Emission from a Young Protostellar Object I. Signatures of Young Embedded Outflows

We examine emission from a young protostellar object (YPO) with threedimensional ideal MHD simulations and three-dimensional non-local thermodynamic equilibrium (non-LTE) line transfer calculations, and show the first results. To calculate the emission field, we employed a snapshot result of an MHD simulation having young bipolar outflows and a dense protostellar disk (a young circumstellar disk) embedded in an infalling envelope.
