 PP-chains
 This reaction network,
pp123.tar.xz, 
contains PP I, II, III and the pep branch.
 
 
 
 
 
 
 CNO cycles
 This reaction network,
cno.tar.xz,
contains CNO cycles I, II, III, and IV.
 
 
 
 
 
 
 PP + CNO
 This reaction network,
ppcno.tar.xz, 
combines the PP and CNO networks.
 
 
 
 
 Ne-Na and Mg-Al Cycles/Chain
 This reaction network was run in 
torch with this 
MESA-style 
isotope specification 
file.
 
 
 
 
 
 
 Hot CNO + rp breakout
 This reaction network,
hotcno.tar.xz, 
adds beta-limited links to the CNO cycle, a few alpha-chain 
reactions up to Ne20, and an rp-process breakout based on the ideas in 
Wallace and Woosley.
 
 
 
 
 
 
 PP + Hot CNO + rp breakout
 This reaction network,
pphotcno.tar.xz, 
combines the PP, CNO, hot CNO, and rp breakout into one reasonably
complete hydrogen burning network.
 
 
 Aprox8
 This reaction network, 
aprox8.tar.xz,
was originally written for 
MESA
and approximates hydrogen (pp+cno), helium, and carbon burning
with only 8 isotopes.
