New 59Fe beta-decay rates in non-rotating MESA models suppress 60Fe yields by 0.28 dex, yielding a Salpeter-IMF-integrated 60Fe/26Al flux ratio of 0.18 that matches the observed 0.184 ± 0.042.

A more efficient 12C+12C rate extends carbon burning, produces less compact pre-supernova structures, and enhances s-process yields of elements heavier than Fe in supernova ejecta from 15-40 solar mass stars.

The Impact of the New $^{59}$Fe Decay Rates on $^{60}$Fe and $^{26}$Al Nucleosynthesis in Massive Stars
New 59Fe beta-decay rates in non-rotating MESA models suppress 60Fe yields by 0.28 dex, yielding a Salpeter-IMF-integrated 60Fe/26Al flux ratio of 0.18 that matches the observed 0.184 ± 0.042.
