Red Spiral: (large, small); Gap Opening Animations: MPG-Movie 1, MPG-Movie 2
The Global View I (Yellow Spiral) : The fully developed gap and the winding spirals (trailing shock waves).
The Global View II: The tenuous spiral arms - extending all the way to the planet. This image was published in Science (Vol. 276, p. 1338, 1997).
The FLOW FIELD:
A Close Up
of the detailed flow field
in the vicinity of the planet.
Note, that the spiral arms are trailing shock waves, and the prograde rotation rate within the planets Roche lobe.
The Migration Rate: Mass accretion onto the planet through the gap, for different numerical parameter.
Torque: Azimuthally averaged torque created by the disk on the planet.
Migration: Change in the distance of the planet from the star.
Gap Opening: Evolution of two planets in the disk.
Radial Evolution: of the two planets.
Two planets orbiting in the center of a protoplanetary disk in a resonance Overview.
Animation of the eccentricity evolution of HD 128311
Evolution of Eccentricities of the two planets for HD 128311. At around t=2500 the planets interact with an inner low mass planet.
Evolution of Eccentricity and Semi-major axis for a GJ 876 Setup.
Evolution of the Resonant Angles for a GJ 876 Setup.
Star Formation: Numerical simulations concerning issues of Star Formation.
Two-Grid Calculation: First result of a 2-Grid calculation with a linear resolution of about 0.0083 around the planet in both r and phi direction.Test Calculations: of the numerical method relating to two-dimensional flat disks. Additional Results: discussing the influence of disk parameters (temperature) on the accretion rate onto the planet.
