| Abstract | dc.description.abstract | In this paper we study the “standardized candle method” using a sample of
37 nearby (redshift z < 0.06) Type II plateau supernovae having BV RI photometry
and optical spectroscopy. An analytic procedure is implemented to fit light
curves, color curves, and velocity curves. We find that the V − I color toward
the end of the plateau can be used to estimate the host-galaxy reddening with a
precision of (AV ) = 0.2 mag. The correlation between plateau luminosity and
expansion velocity previously reported in the literature is recovered. Using this
relation and assuming a standard reddening law (RV = 3.1), we obtain Hubble
diagrams in the BV I bands with dispersions of 0.4 mag. Allowing RV to vary
and minimizing the spread in the Hubble diagrams, we obtain a dispersion range
of 0.25–0.30 mag, which implies that these objects can deliver relative distances
with precisions of 12–14%. The resulting best-fit value of RV is 1.4 ± 0.1. | en_US |
