Rolfs Simulation Highlights
Here some highlight of our simulations performed during the last 10 years are collected. On this page, only brief explanations are given. For more details follow the links to the appropriate web pages. Have fun.

Two examples of how colliding radiative flows contribute to structure formation in space. Curious? Click to get more scientific backgrounds.
Colliding winds in symbiotic binaries

Symbiotics are evolved low-mass binaries with a hot post AGB star as the primary and a RGB star (s-type symbiotics) or an AGB star (d-type symbiotics) as the secondary. In many - if not in all - systems both stars lose mass by stellar winds of higly different characteristics: the fast, tenous wind from the primary interacts with the slow, dense wind from the secondary. The graph shows the logarithmically color-coded 3D density structure of the circumstellar material. The stars are located in the very center of the computational box (black). In this simulation, the stellar separation is about 30 times smaller than the computational box. More scientfic background can be taken from here.
