SNR 1987A : Spitzer data from days 6000 to 8000 revisited
Patrice Bouchet, René Gastaud, Alain Coulais +1
An excess emission has been observed by Spitzer in the [3, 5] micron range of the SNR 1987A spectrum. It is generally argued that this excess could be due to the presence of warm a…
Deep JWST/NIRCam imaging of Supernova 1987A
Mikako Matsuura, M. Boyer, Richard G. Arendt +46
JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
JWST NIRCam Observations of SN 1987A: Spitzer Comparison and Spectral Decomposition
Richard G. Arendt, Martha L. Boyer, Eli Dwek +24
JWST NIRCam observations at 1.5-4.5 m have provided broad and narrow band imaging of the evolving remnant of SN 1987A with unparalleled sensitivity and spatial resolution. Compa…
Final Spitzer IRAC Observations of the Rise and Fall of SN 1987A
Richard G. Arendt, Eli Dwek, Patrice Bouchet +4
Spitzer's final Infrared Array Camera (IRAC) observations of SN 1987A show the 3.6 and 4.5 m emission from the equatorial ring (ER) continues a period of steady decline. Deconvo…
The Evolution of Dust Opacity in Core Collapse Supernovae and the Rapid Formation of Dust in Their Ejecta
Eli Dwek, Arkaprabha Sarangi, Richard. G. Arendt
Infrared (IR) observations of core collapse supernovae (CCSNe) have been used to infer the mass of dust that has formed in their ejecta. A plot of inferred dust masses versus super…
SOFIA mid-infrared observations of Supernova 1987A in 2016 --- forward shocks and possible dust re-formation in the post-shocked region?
Mikako Matsuura, James M. De Buizer, Richard G. Arendt +10
The equatorial ring of Supernova (SN) 1987A has been exposed to forward shocks from the SN blast wave, and it has been suggested that these forward shocks have been causing on-goin…
Delayed Shock-induced Dust Formation in the Dense Circumstellar Shell Surrounding the Type IIn Supernova SN 2010jl
Arkaprabha Sarangi, Eli Dwek, Richard G Arendt
The light curves of Type IIn supernovae are dominated by the radiative energy released through the interaction of the supernova shockwaves with their dense circumstellar medium (CS…
Constraints on the Progenitor of SN 2010jl and Pre-Existing Hot Dust in its Surrounding Medium
Eli Dwek, Richard G. Arendt, Ori D. Fox +6
A search for the progenitor of SN~2010jl, an unusually luminous core-collapse supernova of Type~IIn, using pre-explosion {\it Hubble}/WFPC2 and {\it Spitzer}/IRAC images of the reg…
The Candidate Progenitor of the Type IIn SN 2010jl is Not an Optically Luminous Star
Ori D. Fox, Schuyler D. Van Dyk, Eli Dwek +8
The nature of the progenitor star (or system) for the Type IIn supernova (SN) subclass remains uncertain. While there are direct imaging constraints on the progenitors of at least…
The Evolution of Dust Mass in the Ejecta of SN1987A
Eli Dwek, Richard G. Arendt
We present a new analysis of the infrared (IR) emission from the ejecta of SN1987A covering days 615, 775, 1144, 8515, and 9090 after the explosion. We show that the observations a…
