Data Files

Note that part of the data sets provided below may be preliminary and that part of them could change without notice.
We would appreciate if you contact us before using the data on this site for your publications.

Rotating presupernova models from Heger, Langer, & Woosley (2000)

Non-rotating pre-supernova models from Woosley, Heger, Weaver (2002)

Magnetic rotating presupernova models from Heger, Woosley, & Spruit (2004)

More data files will become available on this site in the future.
Please contact us if your require additional data files or output quantities.

Movies

The movies are composed from a series of Kippenhahn Diagrams, i.e., stellar structure as a function of time, which vary one parameter of the star. All sequences use the same color coding:

	convection
	semiconvection

How to play the movies.

Mass grids for different metallicity

The movies shown here are based on a preliminary test study by A. Heger and S.E. Woosley for an extended new grid of nucleosynthesis in massive stars.

The last 100,000 yr of the inner 10 solar masses of a massive star.

The whole life of a massive star.

C12(a,g) rate study

The movies shown here are based on a thesis project by M.M. Boyes
in collaboration with A. Heger and S.E. Woosley.

The movies magnify the evolution of the helium core starting at end of central helium burning till core collapse.
