Type IIn supernovae (SNe IIn) have been found to be associated with significant amounts of dust. These core-collapse events are generally expected to be the final stage in the evolution of highly massive stars, either while in an extreme red supergiant phase or during a luminous blue variable phase. Both evolutionary scenarios involve substantial pre-supernova mass loss. I have analyzed the SN IIn 1995N in MCG –02–38–017 (Arp 261), for which mid-infrared archival data obtained with the Spitzer…

Early gray dust formation in the type IIn SN 2005ip
The physical characteristics of dust formed in supernovae is poorly known. In this paper, we investigate the extinction properties of dust formed in the type IIn SN 2005ip. The observed light curves
Supernova 2014C: Ongoing Interaction with Extended Circumstellar Material with Silicate Dust
Supernova (SN) 2014C is a unique explosion where a seemingly typical hydrogen-poor stripped envelope SN started to interact with a dense, hydrogen-rich circumstellar medium (CSM) a few months after
Spitzer’s Last Look at Extragalactic Explosions: Long-term Evolution of Interacting Supernovae
Here we present new, yet final, mid-infrared (mid-IR) data for supernovae (SNe) based on measurements with the Spitzer Space Telescope. Comparing our recent 3.6 and 4.5 μm photometry with previously
Type IIn Supernovae
In this chapter discusses supernovae of Type IIn (SN IIn), the distinguishing characteristic of which is the presence of narrow spectral lines of hydrogen, indicative of circumstellar interaction.
A Comprehensive Analysis of Spitzer Supernovae
The mid-infrared (mid-IR) wavelength regime offers several advantages for following the late-time evolution of supernovae (SNe). First, the peaks of the SN spectral energy distributions shift toward
SOFIA Observations of SN 2010jl: Another Non-Detection of the 9.7 μm Silicate Dust Feature
We present photometric observations from the Stratospheric Observatory for Infrared Astronomy (SOFIA) at 11.1 micrometers of the Type IIn supernova (SN IIn) 2010jl. The SN is undetected by SOFIA, but
Observational Limits on the Early-time Dust Mass in SN 1987A
In recent years, dust masses of a few tenths of a solar mass have been found in the expanding ejecta of a number of core-collapse supernovae. How dust forms in such quantities remains poorly
Rapid formation of large dust grains in the luminous supernova 2010jl
The rapid formation of dust in the bright SN 2010jl and the wavelength-dependent extinction of this dust reveals the presence of very large grains, which resist destruction, providing the link between the early and late dust mass evolution in supernovae with dense circumstellar media.
Dust in Supernovae and Supernova Remnants I: Formation Scenarios
Supernovae are considered as prime sources of dust in space. Observations of local supernovae over the past couple of decades have detected the presence of dust in supernova ejecta. The reddening of
The candidate luminous blue variable G79.29+0.46: a comprehensive study of its ejecta through a multiwavelength analysis
We present a multiwavelength analysis of the nebula around the candidate luminous blue variable G79.29+0.46. The study is based on our radio observations performed at the Expanded Very Large Array


Dust and the Type II-Plateau Supernova 2004et
We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the Spitzer Space Telescope between 64 and 1406 days past explosion. Late-time optical spectra
Evidence for Pre-existing Dust in the Bright Type IIn SN?2010jl
SN 2010jl was an extremely bright, Type IIn supernova (SN) which showed a significant infrared (IR) excess no later than 90 days after explosion. We have obtained Spitzer 3.6 and 4.5 μm and JHK
A Spitzer Survey for Dust in Type IIn Supernovae
Recent observations suggest that Type IIn supernovae (SNe IIn) may exhibit late-time (>100?days) infrared (IR) emission from warm dust more than other types of core-collapse SNe. Mid-IR observations,
A Spitzer Space Telescope Study of SN 2003gd: Still No Direct Evidence that Core-Collapse Supernovae are Major Dust Factories
We present a new, detailed analysis of late-time mid-infrared observations of the Type II-P supernova (SN) 2003gd. At about 16 months after the explosion, the mid-IR flux is consistent with emission
Supernova 1998S at 14 years postmortem: continuing circumstellar interaction and dust formation
We report late-time spectroscopic observations of the Type IIn supernova (SN) 1998S, taken 14 years after explosion using the Large Binocular Telescope. The optical spectrum exhibits strong, broad
Extraordinary Late-Time Infrared Emission of Type IIn Supernovae
Near-infrared observations are presented for five Type IIn supernovae (SN 1995N, SN 1997ab, SN 1998S, SN 1999Z, and SN 1999el) that exhibit strong infrared excesses at late times (t 100 days). H- and
Dust Formation and He II λ4686 Emission in the Dense Shell of the Peculiar Type Ib Supernova 2006jc
We present evidence for the formation of dust grains in an unusual Type Ib supernova (SN) based on late-time spectra of SN 2006jc. The progenitor suffered an outburst qualitatively similar to those
A Search for Infrared Emission from Core-Collapse Supernovae at the Transitional Phase
Most of the observational studies of supernova (SN) explosions are limited to early phases ( 100 yr) in our Galaxy or very nearby galaxies. SNe at the epoch between these two, which we call
