Relative frequencies of Type Ia and Type II supernovae in the chemical evolution of the Galaxy, LMC and SMC
Open accessAbstract
The predicted nucleosynthesis products of Type Ia and Type II supernovae are combined with various parameter ratios and compared with the solar abundances of heavy elements and their isotopes, and also with the abundances of heavy elements in the LMC and SMC. Aided by a reasonable model of galactic chemical evolution, the ratio of the total numbers (of all time) of Type Ia to Type II supernovae that best reproduces the observed abundances is determined to be NIa/NII = 0.15 for the Galaxy, in agreement with current observations. For the MCs, however, this ratio is larger than that for the Galaxy, yielding NIa/NII = 0.2–0.3. We discuss several possible star formation history scenarios that may account for such an enhanced frequency of Type Ia supernovae in the MCs.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
