Abstract:
We age-date the stellar populations associated with 12 historic nearby
core-collapse supernovae (CCSNe) and two supernova impostors; from
these ages, we infer their initial masses and associated
uncertainties. To do this, we have obtained new Hubble Space Telescope
imaging covering these CCSNe. Using these images, we measure resolved
stellar photometry for the stars surrounding the locations of the SNe.
We then fit the color-magnitude distributions of this photometry with
stellar evolution models to determine the ages of any young existing
populations present. From these age distributions, we infer the most
likely progenitor masses for all of the SNe in our sample. We find
ages between 4 and 50Myr, corresponding to masses from 7.5 to
59M☉. There were no SNe that lacked a local young population.
Our sample contains four SNe Ib/c; their masses have a wide range of
values, suggesting that the progenitors of stripped-envelope SNe are
binary systems. Both impostors have masses constrained to be
≲7.5M☉. In cases with precursor imaging measurements, we find
that age-dating and precursor imaging give consistent progenitor
masses. This consistency implies that, although the uncertainties for
each technique are significantly different, the results of both are
reliable to the measured uncertainties. We combine these new
measurements with those from our previous work and find that the
distribution of 25 core-collapse SNe progenitor masses is consistent
with a standard Salpeter power-law mass function, no upper mass
cutoff, and an assumed minimum mass for core-collapse of 7.5M☉.
The distribution is consistent with a minimum mass <9.5M☉.
Description:
We obtained new observations with HST of 12 nearby core-collapse
supernovae (CCSNe) and two supernova impostors with known spectral
types under the program GO-14786, in 2015 oct, 2016 Oct and Nov and
2017 Jan. We observed with ACS/WFC and WFC3/UVIS in parallel, to
provide the largest possible coverage of the host galaxies.
See section 2.2.

except SN1954A and SN2003gd, which were taken from
Pietra (1955MmSAI..26..185P 1955MmSAI..26..185P) and Maund & Smartt (2009Sci...324..486M 2009Sci...324..486M),
respectively.
Note (2): The distances in the table are updated to include only those from the
tip of the red giant branch (TRGB), which are the most appropriate to
use for CMD fitting because it minimizes systematic offsets between
the stellar evolution models and CMD features. See section 2.1.
Note (3): Reference as follows:
a = Karachentsev+ (2000A&A...362..544K 2000A&A...362..544K), consistent with
Tikhonov (2014AstL...40..537T 2014AstL...40..537T).

d = Karachentsev+ (2013, J/AJ/145/101).
e = Jang & Lee (2014ApJ...792...52J 2014ApJ...792...52J). This TRGB distance is farther than
previously published distances, and is consistent with our data, which
find only two main-sequence stars for constraining each of these
progenitor masses.
f = Monachesi+ (2016MNRAS.457.1419M 2016MNRAS.457.1419M).
Note (4): Flag as follows:
b = This likely impostor had no significant young population within 50pc.
a = These SNe had probability distributions with multiple significant
peaks. Only the most prominent peak is represented here. See Table 4
