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).
