Abstract:
We present optical and near-infrared photometry and spectroscopy of
SN 2009ib, a Type II-P supernova in NGC 1559. This object has moderate
brightness, similar to those of the intermediate-luminosity SNe 2008in
and 2009N. Its plateau phase is unusually long, lasting for about 130d
after explosion. The spectra are similar to those of the subluminous
SN 2002gd, with moderate expansion velocities. We estimate the 56Ni
mass produced as 0.046±0.015M☉. We determine the distance to
SN 2009ib using both the expanding photosphere method (EPM) and the
standard candle method. We also apply EPM to SN 1986L, a Type II-P SN
that exploded in the same galaxy. Combining the results of different
methods, we conclude the distance to NGC 1559 as D=19.8±3.0Mpc. We
examine archival, pre-explosion images of the field taken with the
Hubble Space Telescope, and find a faint source at the position
of the SN, which has a yellow colour [(V-I)0=0.85mag]. Assuming
it is a single star, we estimate its initial mass as MZAMS=20M☉.
We also examine the possibility, that instead of the yellow source the
progenitor of SN 2009ib is a red supergiant star too faint to be
detected. In this case, we estimate the upper limit for the initial
zero-age main sequence (ZAMS) mass of the progenitor to be ∼14-17M☉.
In addition, we infer the physical properties of the progenitor at the
explosion via hydrodynamical modelling of the observables, and estimate
the total energy as ∼0.55x1051erg, the pre-explosion radius as
∼400R☉, and the ejected envelope mass as ∼15M☉, which implies
that the mass of the progenitor before explosion was ∼16.5-17M☉.
Description:
Optical photometry was collected using multiple telescopes with UBVRI
and u'g'r'i'z' filters, covering the phases between 13 and 262d after
explosion. The basic reduction steps of the images (such as
bias-subtraction, overscan-correction, flat-fielding) were carried out
using the standard IRAF tasks. The photometric measurement of the SN
was performed using the point-spread function (PSF) fitting technique
via the SNOOPY package in IRAF.
Near-infrared photometry was obtained using the Rapid Eye Mount (REM)
telescope in JH bands. Dithered images of the SN field were taken in
multiple sequences of five. The object images were dark- and flat-field
corrected, combined to create sky images then the sky images were
subtracted from the object images. The images were then registered and
combined.
