Abstract

We simulate the surface brightness of the HH 30 astrophysical jet near its launch site in the forbidden [O I], [N II], and [S II] doublets by post-processing gas dynamical simulations of densities and temperatures, using spectral line emission data from the astrophysical spectral synthesis package Cloudy. We then compare the simulated surface brightness in each line with Hubble Space Telescope observations of Hartigan and Morse and with multiple-ion magnetohydrodynamic simulations of Tesileanu et al. The general trend of our simulated surface brightness in each doublet using the gas dynamical/Cloudy approach is in excellent agreement with the observational data, verifying our choices of initial jet and ambient densities and jet temperature, as well as the number and sequencing of the jet pulses over the 35 year evolution of the jet near its launch site.
