Abstract:
Using resolved optical stellar photometry from the Panchromatic Hubble
Andromeda Treasury Triangulum Extended Region (PHATTER) survey, we
measured the star formation history near the position of 85 supernova
remnants (SNRs) in M33. We constrained the progenitor masses for 60 of
these SNRs, finding that the remaining 25 remnants had no local star
formation in the last 56Myr, consistent with core-collapse supernovae,
making them potential Type Ia candidates. We then infer a progenitor
mass distribution from the age distribution, assuming single star
evolution. We find that the progenitor mass distribution is consistent
with being drawn from a power law with an index of -2.9-1.0+1.2.
Additionally, we infer a minimum progenitor mass of
7.1-0.2+0.1M☉ from this sample, consistent with several
previous studies, providing further evidence that stars with ages
older than the lifetimes of single 8M☉ stars are producing
supernovae.
