Direct Imaging of Exoplanets with Adaptive Optics, Coronagraphy, and Differential Imaging
Not a povray animation, but it shows the interesting aspects of trying to image an extrasolar planet from the ground: Atmospheric turbulence is corrected by so-called adaptive optics on modern telescopes. The animation shows a "normal" observation on the left,
Planet Formation in Circumstellar Disk
upiter-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 HH 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 ...
