Abstract:
We present an observational study of the Type IIn supernovae (SNe IIn)
2005ip and 2006jd. Broadband UV, optical, and near-IR photometry, and
visual-wavelength spectroscopy of SN 2005ip complement and extend upon
published observations to 6.5 years past discovery. Our observations
of SN 2006jd extend from UV to mid-infrared wavelengths, and like
SN 2005ip, are compared to reported X-ray measurements to understand
the nature of the progenitor. Both objects display a number of
similarities with the 1988Z-like subclass of SN IIn including (1)
remarkably similar early- and late-phase optical spectra, (2) a
variety of high-ionization coronal lines, (3) long-duration optical
and near-IR emission, and (4) evidence of cold and warm dust
components. However, diversity is apparent, including an unprecedented
late-time r-band excess in SN 2006jd. The observed differences are
attributed to differences between the mass-loss history of the
progenitor stars. We conclude that the progenitor of SN 2006jd likely
experienced a significant mass-loss event during its pre-SN evolution
akin to the great 19th century eruption of η Carinae. Contrarily,
as advocated by Smith et al., the circumstellar environment of SN
2005ip is found to be more consistent with a clumpy wind progenitor.
Description:
Here we present Carnegie Supernova Project (CSP; Hamuy et al.
2006PASP..118....2H 2006PASP..118....2H) optical (uBgVri) and near-IR (YJH) light curves
of SN 2005ip and SN 2005jd. The majority of our imaging was obtained
at the Las Campanas Observatory (LCO) with the Henrietta Swope 1.0m
telescope. These data are accompanied with additional imaging taken
with the Irenee du Pont 2.5m telescope.
SN 2005ip was discovered on 5.2 November 2005 UT in the Scd galaxy
NGC 2906 (see Figure 1). Our photometric monitoring began four days
after discovery, and extend 5.3 years, with the last near-IR
observations obtained on 21.1 February 2011 UT. In addition to the
photometric follow-up, 13 epochs of low-resolution visual-wavelength
spectroscopy of SN 2005ip covering the first five and a half months
(2005 November 23-2006 April 23) of evolution was obtained with an
assortment of telescopes at LCO and the La Silla Observatory.
SN 2006jd was discovered on 12.5 October 2006 UT in the SBb galaxy
UGC 4179 by the Lick Observatory Supernova Search (figure 2). Our
photometric observations commenced a week after discovery and extend
over a duration of nearly four and a half years. Seventeen epochs of
low-resolution, long-slit visual-wavelength spectroscopy of SN 2006jd
were obtained with an assortment of telescopes at LCO, and the La
Silla and Mauna Kea Observatories.

Note on table1.dat: SN photometry is computed differentially with respect to a
local sequence of stars. Absolute photometry of the optical and near-IR local
sequence of SN 2005ip was determined relative to photometric standard stars
observed over the course of six and (a minimum of) nine photometric nights,
respectively. The local sequence of stars used to compute SN 2006jd
photometry was calibrated with respect to standard field observations
obtained on 11 nights in the optical and, depending on the specific star,
between 3 and 22 nights in the near-IR.
