JWST/MIRI Observations of Newly Formed Dust in the Cold, Dense Shell of the Type IIn SN 2005ip
Melissa Shahbandeh, Ori D. Fox, Tea Temim +42
Dust from core-collapse supernovae (CCSNe), specifically Type IIP SNe, has been suggested to be a significant source of the dust observed in high-redshift galaxies. CCSNe eject lar…
Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI
Szanna Zsíros, Tamás Szalai, Ilse De Looze +39
We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…
Evidence for late-time dust formation in the ejecta of supernova SN~1995N from emission-line asymmetries
R. Wesson, A. M. Bevan, M. J. Barlow +4
We present a study of the dust associated with the core-collapse supernova SN~1995N. Infrared emission detected 14--15 years after the explosion was previously attributed to therma…
Quantifying the dust in SN 2012aw and iPTF14hls with ORBYTS
Maria Niculescu-Duvaz, M. J. Barlow, W. Dunn +32
Core-collapse supernovae (CCSNe) are potentially capable of producing large quantities of dust, with strong evidence that ejecta dust masses can grow significantly over extended pe…
Dust masses for a large sample of core-collapse supernovae from optical emission line asymmetries: dust formation on 30-year timescales
Maria Niculescu-Duvaz, Michael J Barlow, Antonia Bevan +7
Modelling the red-blue asymmetries seen in the broad emission lines of core-collapse supernovae (CCSNe) is a powerful technique to quantify total dust mass formed in the ejecta at…
The dawn of a new era for dustless HdC stars with GAIA eDR3
P. Tisserand, C. L. Crawford, G. C. Clayton +7
Decades after their discovery, only four hydrogen-deficient carbon (HdC) stars were known to have no circumstellar dust shell. This is in complete contrast to the 130 known G…
The infrared view of dust and molecules around V4334 Sgr (Sakurai's Object): a 20-year retrospective
A. Evans, R. D. Gehrz, C. E. Woodward +16
We present an analysis of the evolution of circumstellar dust and molecules in the environment of the very late thermal pulse object V4334 Sgr (Sakurai's Object) over a -ye…
A First Transients Survey with JWST: the FLARE project
Lifan Wang, D. Baade, E. Baron +43
JWST was conceived and built to answer one of the most fundamental questions that humans can address empirically: "How did the Universe make its first stars?". Our First Lights At…
On the metallicity dependence of crystalline silicates in oxygen-rich asymptotic giant branch stars and red supergiants
O. C. Jones, F. Kemper, B. A. Sargent +10
We investigate the occurrence of crystalline silicates in oxygen-rich evolved stars across a range of metallicities and mass-loss rates. It has been suggested that the crystalline…
The Dust Budget of the SMC: Are AGB Stars the Primary Dust Source at Low Metallicity?
Martha L. Boyer, S. Srinivasan, D. Riebel +7
We estimate the total dust input from the cool evolved stars in the Small Magellanic Cloud (SMC), using the 8 micron excess emission as a proxy for the dust-production rate. We fin…
Solid-phase C_60 in the peculiar binary XX Oph?
A. Evans, J. Th. van Loon, C. E. Woodward +8
We present infrared spectra of the binary XX Oph obtained with the Infrared Spectrograph on the Spitzer Space Telescope. The data show some evidence for the presence of solid C_60…
