Grids of Stellar Evolution Models
The internal stellar evolution
of massive stars from from hydrogen burning till core collapse
is shown using "Kippenhahn" diagrams.
We show the stellar evolution as a function of stellar mass and
also demonstrate the influence of one key nuclear reaction rate,
C12(a,g).

Convection_Ra9.mpg
(6.5 MB)This is a movie of the entropy in 2d convection with
periodic side boundaries and isentropic top and bottom
boundaries. The Rayleigh number in this calculation is 1.d9 and
the prandtl number is 0.1, clearly in the turbulent regime. As
expected in 2d the small scale structure cascades to the large
scale "roll".

(Warning 32 MB)This is a movie of the entropy in 2d
convection with periodic side boundaris and isentropic top and bottom
boundaries. The Rayleigh number in this calculation is 1.d10 and the
prandtl number is 0.1, clearly in the turbulent regime. In this
calculation the small scale structure cascades to the large scale
"roll" as expected in 2d.
