Galactic chemical evolution and extinct/extant radiochronometers
If stellar yields are known, models of galactic chemical evolution can
be used to predict what the abundances of extinct and extant
radionuclides at the formation of the solar system were. These
predictions can be compared with meteorite measurements to constrain
some aspects of stellar nucleosynthesis and galactic chemical
evolution. The questions that will be addressed are
(i) What is the radiometric age of the Galaxy?
(ii) Did X-ray binaries contribute a significant portion of p-process
nuclides in the solar system?
(iii) Is there evidence in meteoritic abundances for multiple sites for
