| Research Abstract |
Observational visualization is a method to obtain expected observational features for the outcome from (magneto)hydrodynamical simulations. This enables us to compare directly simulation results and observations. Polarization of the thermal emissions from interstellar dusts is calculated for pre- and protostellar cores and molecular outflows. We are now able to estimate the 3-dimensional magnetic field configuration from the 2-dimensional polarization pattern. Using the non-local thermal equilibrium (NonLTE) radiation transfer calculation, we have found observational features characteristic to the early phase of protostar formation.
