cds-question@unistra.frsupernova-remnantshst-photometrygalaxiesstellar-massesstellar-agesvisible-astronomysurveysUsing 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_^+0.1^M_{sun}_ from this sample, consistent with several previous studies, providing further evidence that stars with ages older than the lifetimes of single 8M_{sun}_ stars are producing supernovae.2023ApJ...949...32Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/949/32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)J/ApJS/120/247 : Supernova remnants in M33 (Gordon+, 1999)J/MNRAS/395/1409 : Type II-P SN progenitor constraints (Smartt+, 2009)J/ApJS/187/495 : SNRs in M33 from optical and X-ray (Long+, 2010)J/ApJ/795/170 : Sample SNRs for M31 and M33 (Jennings+, 2014)J/ApJ/793/134 : M33 SNR candidates properties (Lee+, 2014)J/ApJ/786/130 : Catalog of M31 SNR candidates (Lee+, 2014)J/ApJ/789/147 : Star formation histories of LG dwarf galaxies (Weisz+, 2014)J/ApJ/791/105 : SNe progenitor masses prob. distribution (Williams+, 2014)J/ApJ/846/145 : PHAT.
