“…Given the uncertainties involved in the derivations, it is encouraging to note that these estimates are consistent with the dust masses computed for other SNe IIn (e.g., Gerardy et al 2002;Pozzo et al 2004;Meikle et al 2007;Trundle et al 2009;Andrews et al 2011;Gall et al 2011), and the Type Ibn SN 2006jc (Smith et al 2008b;Di Carlo et al 2008;Nozawa et al 2008;Mattila et al 2008;Anupama et al 2009;Sakon et al 2009). …”

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) longduration 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.

“…Dust formation has been observed in SN 2006jc early on, at ∼50 d past maximum (Di Carlo et al 2008; Nozawa et al 2008; Smith et al 2008). Dust formation is reflected in the helium emission line profiles, which developed an asymmetric profile, with the red wing of the profile getting increasingly suppressed with time, and also in the increase in the red to NIR continuum between 65 and 120 d. Smith et al (2008) estimate the dust temperature during this phase to be ∼1600 K. The estimated densities in the shell are high enough to precipitate graphite dust (Clayton 1979).…”

We present optical UBVRI photometric and spectroscopic data of the Type Ibn supernova SN 2006jc, until the onset of the dust‐forming phase. The optical spectrum shows a blue continuum and is dominated by the presence of moderately narrow (velocity ∼2500 km s−1) He i emission lines superimposed over a relatively weak supernova spectrum. The helium lines are produced in a pre‐existing He‐rich circumstellar shell. The observed helium line fluxes indicate the circumstellar shell is dense, with a density of ∼109–1010 cm−3. The helium mass in this shell is estimated to be ≲0.07 M⊙. The optical light curves show a clear signature of dust formation, indicated by a sharp decrease in the magnitudes around day 50, accompanied by a reddening of the colours. The evolution of the optical light curves during the early phase and that of the uvoir bolometric light curve at all phases is reasonably similar to normal Ib/c supernovae.

“…Within the CDS conditions can allow new dust to form (Pozzo et al 2004). CDS dust has been invoked as the origin of the early-time IR excess of SN 2006jc (Smith et al 2008;Di Carlo et al 2008;Mattila et al 2008). Mattila et al (2008) showed that the IR emission was probably an IR echo from the CDS dust.…”

We present mid-infrared (MIR) spectroscopy of a Type II-plateau supernova, SN 2004dj, obtained with the Spitzer Space Telescope, spanning 106-1393 days after explosion. MIR photometry plus optical/near-IR observations are also reported. An early-time MIR excess is attributed to emission from non-silicate dust formed within a cool dense shell (CDS). Most of the CDS dust condensed between 50 days and 165 days, reaching a mass of 0.3 × 10 −5 M . Throughout the observations, much of the longer wavelength (>10 μm) part of the continuum is explained as an IR echo from interstellar dust. The MIR excess strengthened at later times. We show that this was due to thermal emission from warm, non-silicate dust formed in the ejecta. Using optical/near-IR line profiles and the MIR continua, we show that the dust was distributed as a disk whose radius appeared to be shrinking slowly. The disk radius may correspond to a grain destruction zone caused by a reverse shock which also heated the dust. The dust-disk lay nearly face-on, had high opacities in the optical/near-IR regions, but remained optically thin in the MIR over much of the period studied. Assuming a uniform dust density, the ejecta dust mass by 996 days was (0.5 ± 0.1) × 10 −4 M and exceeded 10 −4 M by 1393 days. For a dust density rising toward the center the limit is higher. Nevertheless, this study suggests that the amount of freshly synthesized dust in the SN 2004dj ejecta is consistent with that found from previous studies and adds further weight to the claim that such events could not have been major contributors to the cosmic dust budget.
