Abstract:
We study a sample of 11 Type II supernovae (SNe) discovered by the
OGLE-IV survey. All objects have well-sampled I-band light curves, and
at least one spectrum. We find that two or three of the 11 SNe have a
declining light curve, and spectra consistent with other SNe II-L,
while the rest have plateaus that can be as short as 70 d, unlike the
100 d typically found in nearby galaxies. The OGLE SNe are also
brighter, and show that magnitude-limited surveys find SNe that are
different than usually found in nearby galaxies. We discuss this
sample in the context of understanding Type II SNe as a class and
their suggested use as standard candles.
Description:
Out of the SNe in Wyrzykowski et al. (2014, J/AcA/64/197), we focus on
objects that can be spectroscopically classified as Type II, either
II-P or II-L, avoiding SNe of Type IIn and IIb. We further excluded
objects with a light curve that was clearly IIb-like (i.e. similar to
SN 1993J; Richmond et al. 1994, J/AJ/107/1022). Since most of our
objects only have one spectrum, and it was often taken early, we may
have some interloping SN IIb in the sample. Most of the spectra were
acquired by the PESSTO project (Smartt et al. 2015A&A...579A..40S 2015A&A...579A..40S), and
downloaded from WISEREP (Yaron & Gal-Yam 2012PASP..124..668Y 2012PASP..124..668Y), except for
OGLE13-0051 which was observed and classified by Prieto & Morrell
(2013ATel.4734....1P 2013ATel.4734....1P).
