As a coda, it’s important to note that HH212 has been studied intensively by many others since we discovered it, including a whole series of impressive papers looking at the inner jet & circumstellar disk by Chin-Fei Lee & Claudio Codella & their respective collaborators, using ALMA at millimetre wavelengths.
There’s amazing detail down in the region near the core where we’re blocked by dust, but they see the jet being launched by magnetic fields.
We’ll cite all that work in our paper
