Emission Signatures of a Young Embedded Protostellar Object

| We examine emission signature of a young protostellar object deeply embedded in the infalling envelope with three-dimensional MHD simulations and non-LTE line transfer calculations. The velocity field consists of infall, rotation and outflow motions introduces a great complexity in the line emission fields through optical thickness and emissivity. We find that one of the characteristics of an outflow driven by magneto-centrifugal force appears in velocity channel maps and intensity-weighted mean velocity. Further experiments with resistive MHD simulations show that morphology of the very young outflows can be an observable indicator of magnetic flux dissipation. We will show a suite of "telescope of theory" from MHD modeling to imaging simulation of the synthesized emission for ALMA, or pseudo observation results in computer. | |
