Abstract:
We study a sample of 23 Type II plateau supernovae (SNe II-P), all
observed with the same set of instruments. Analysis of their
photometric evolution confirms that their typical plateau duration is
100 d with little scatter, showing a tendency to get shorter for more
energetic SNe. We examine the claimed correlation between the
luminosity and the rise time from explosion to plateau. We analyse
their spectra, measuring typical ejecta velocities, and confirm that
they follow a well-behaved power-law decline. We find indications of
high-velocity material in the spectra of six of our SNe. We test
different dust-extinction correction methods by asking the following -
does the uniformity of the sample increase after the application of a
given method? A reasonably behaved underlying distribution should
become tighter after correction. No method we tested made a
significant improvement.
Description:
Imaging was obtained with the 0.76m Katzman Automatic Imaging
Telescope (KAIT), the SN search engine of LOSS. The sample was
compiled from events for which precise photometry could be obtained -
that is, for which template images were obtained after the SN had
faded.
