Starmatrix

Modelling nucleosynthesis of galactic chemical elements

Starmatrix is a Q-Matrix generator.

Based on explicit values for solar abundances, Z and IMF, Starmatrix calculates matrices Q(i,j) of masses of elements i ejected to the galactic medium as element j, for a complete range of stellar masses, accounting for supernovae of types I and II.

A technique based on the Q-matrix formalism (Talbot & Arnett, 1973; Ferrini et al., 1992; Portinari et al., 1998) is used to calculate the elemental abundances.

Starmatrix computes the contribution matrix of 15 elements:

H

D

He3

He4

C

C13

N

O

Ne

Mg

Si

S

Ca

Fe

and neutron rich isotopes (referred as n.r. in the code).
