Abstract:
We present a systematic analysis of 191 stripped-envelope supernovae
(SE SNe), aimed at computing their 56Ni masses from the luminosity in
their radioactive tails (MNitail) and/or in their maximum light,
and the mean 56Ni and iron yields of SE SNe and core-collapse SNe.
Our sample consists of SNe IIb, Ib, and Ic from the literature and
from the Zwicky Transient Facility Bright Transient Survey. To
calculate luminosities from optical photometry, we compute bolometric
corrections using 49 SE SNe with optical and near-IR photometry, and
develop corrections to account for the unobserved UV and IR flux. We
find that the equation of Khatami & Kasen (2019ApJ...878...56K 2019ApJ...878...56K) for
radioactive 56Ni-powered transients with a single free parameter
does not fit the observed peak time-luminosity relation of SE SNe.
Instead, we find a correlation between MNitail, peak time, peak
luminosity, and decline rate, which allows for measuring individual
56Ni masses to a precision of 14%. Applying this method to the whole
sample, we find, for SNe IIb, Ib, and Ic, mean 56Ni masses of
0.066±0.006, 0.082±0.009, and 0.132±0.011M☉,
respectively. After accounting for their relative rates, for SE SNe as
a whole, we compute mean 56Ni and iron yields of 0.090±0.005 and
0.097±0.007M☉, respectively. Combining these results with
the recent Type II SN mean 56Ni mass derived by
Rodriguez+ (2021MNRAS.505.1742R 2021MNRAS.505.1742R), core-collapse SNe, as a whole, have
mean 56Ni and iron yields of 0.055±0.006 and
0.058±0.007M☉, respectively. We also find that radioactive
56Ni-powered models typically underestimate the peak luminosity of SE
SNe by 60%-70%, suggesting the presence of an additional power source
contributing to the luminosity at peak.
Description:
For this work, we select SNe IIb, Ib, and Ic (including SNe Ic-BL)
from the literature and from the Zwicky Transient Facility (ZTF)
Bright Transient Survey (BTS; Fremling+ 2020, J/ApJ/895/32;
Perley+ 2020ApJ...904...35P 2020ApJ...904...35P).
For the selected SNe, we collect UV, optical, and IR photometry, along
with optical and IR spectroscopy.
