      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).

Tami Rogers' Movies

• 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".
• Convection_Ra10.mpg (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.

	Hydrodynamic model of a SN collapse and explosion Credit: Adam Burrows & John Hayes Comments: The top set of images links to a movie that follows the initial stages of the core collapse. The bottom set links to a movie, which begins near the end of the previous movie, and the scale has been enlarged to follow the multi-dimensional explosion. Publication:   Burrows et al. 1995
	Hydrodynamic model of a SN collapse and explosion Credit: Adam Burrows & John Hayes Comments: The colors indicate the electron fraction (Ye) Publication:   Burrows et al. 1995
	Hydrodynamic Model of a SNIa blast interacting with a main sequence star I Credit: Evonne Marietta Comments: These results were featured on the cover of Nature in Feb. 2000. Publication:   Marietta et al. 2000
	Hydrodynamic Model of a SNIa blast interacting with a main sequence star II Credit: Evonne Marietta Comments: This movie is different from the one above in that the distance between the exploding star and the companion star is greater. Publication:   Marietta et al. 2000
	Hydrodynamic Model of a SNIa blast interacting with a main sequence star III Credit: Evonne Marietta Comments: This movie focusses on the inner interaction regions during the impact with a main sequence star. In addition, the velocity is represented by a vector field Publication:   Marietta et al. 2000

• This is a 6.7 MB MPEG movie.
  Not big enough? Try these: 19.4 MB, 23.8 MB.
  Want other formats? 2.3 MB mpeg4 avi and 1.1 MB quicktime (Thank Alex Heger for doing the conversion to the quicktime movie)
  
  The movie shows a three-dimensional simulation of a relativistic jet from a collapsar breaking out of the star. Black and blue represent lower density, white and yellow higher density. The calculation was performed on SEABORG at the National Energy Research Scientific Computing Center at Lawrence Berkeley Laboratory (NERSC).
