Numerical simulation of surface brightness of astrophysical jets
Abstrak
We outline a general procedure for simulating the surface brightness of astrophysical jets (and other astronomical objects) by post-processing gas dynamical simulations of densities and temperatures using spectral line emission data from the astrophysical spectral synthesis package {\em Cloudy}. Then we validate the procedure by comparing the simulated surface brightness of the HH~30 astrophysical jet in the forbidden [O~I], [N~II], and [S~II] doublets with {\em Hubble Space Telescope}\/ observations of Hartigan and Morse and multiple-ion magnetohydrodynamic simulations of Tesileanu et al. The general trend of our simulated surface brightness in each doublet using the gas dynamical/{\em Cloudy}\/ approach is in excellent agreement with the observational data.
