Extragalactic jet interacting with a 3 Gyr AGB star at its highest mass-loss rate.
The jet plasma is flowing in from the left.
The global pressure maps depict a bow shock region established upstream
of the contact discontinuity.
The tracer of the jet mass fraction shows
a sharp decrease at the contact discontinuity.
The wake shows von Kármán-like vortices,
which in three dimensions would evolve into downstream turbulence.
