A Jupiter-Mass planet opens a gap in a solar nebula. The gas around the
planet is heated by the accretion of mass onto the planetary surface.
The simulation was done by H.H. Klahr and W. Kley at the University of
Tübingen.
The ray tracer used is PovRay 3.5. The purpose of this tracing is not
a physical model that accurately reproduces photometry at various
wavelengths or other fancy physical parameters. The idea is to
visualize the development of density and size scales during the
collapse. No dust model (opacities, size distribution etc.) is assumed
for the ray tracer. The colours seen in the image do not correspond to
any actual wavelengths.
