Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
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,…
Filamentary Network and Magnetic Field Structures Revealed with BISTRO in the High-Mass Star-Forming Region NGC2264 : Global Properties and Local Magnetogravitational Configurations
Jia-Wei Wang, Patrick M. Koch, Seamus D. Clarke +154
We report 850 m continuum polarization observations toward the filamentary high-mass star-forming region NGC 2264, taken as part of the B-fields In STar forming Regions Observat…
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…
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…
Dust survival rates in clumps passing through the Cas A reverse shock -- II. The impact of magnetic fields
Florian Kirchschlager, Franziska D. Schmidt, M. J. Barlow +2
Dust grains form in the clumpy ejecta of core-collapse supernovae where they are subject to the reverse shock, which is able to disrupt the clumps and destroy the grains. Important…
