Abstract:
This is the first paper of a series aiming to determine the fractions
and birth rates of various types of supernovae (SNe) in the local
Universe. In this paper, we aim to construct a complete sample of SNe
in the nearby universe and provide more precise measurement of subtype
fractions. We carefully selected our SN sample at a distance of <40Mpc
mainly from wide- field surveys conducted over the years from 2016 to
2023. The sample contains a total of 211 SNe, including 109 SNe II, 69
SNe Ia, and 33 SNe Ibc. With the aid of sufficient spectra, we can
obtain relatively accurate subtype classifications for all SNe in this
sample. After corrections for the Malmquist bias, this volume-limited
sample gives fractions of SNe Ia, SNe Ibc, and SNe II as
30.4+3.7-11.5%, 16.3+3.7-7.4%, and 53.3+9.5-18.7%,
respectively. In the SN Ia sample, the fraction of the 91T-like
subtype becomes relatively low (∼5.4%), while that of the 02cx-like
subtype shows a moderate increase (∼6.8%). In the SN Ibc sample, we
find significant fractions of broadlined SNe Ic (∼18.0%) and SNe Ibn
(∼8.8%). The fraction of 87A-like subtype is determined as ∼2.3%,
indicating rare explosions from blue supergiant stars. We find that
SNe Ia show a double peak number distribution in S0- and Sc-type host
galaxies, which may serve as a straightforward evidence for the
presence of 'prompt' and 'delayed' progenitor components giving rise
to SN Ia explosions. Several subtypes of SNe such as 02cx-like SNe Ia,
broadlined SNe Ic, SNe IIn (and perhaps SNe Ibn) are found to occur
preferentially in less massive spiral galaxies, favoring their
associations with young stellar progenitors. Moreover, the 02cx-like
subtype shows a trend of exploding in the outer skirt of their hosts,
suggestive of metal-poor progenitors.
Description:
The nearby SN catalog was established based on the discoveries made
over the period from year 2016 to 2023 when the SN searches enter into
the wide-field survey era. The host galaxy catalog was accordingly
built for the 40-Mpc SN sample, which contains a total of 191
galaxies.
