The outer rings of SN 1987A from year 1994 to 2024: morphology, light curves, and optical to mid-infrared spectra

Sophie Rosu, Elko Gerville-Reache, Steven Thomas +14

The outer rings (ORs) of Supernova (SN) 1987A were ejected ~20000 years before the explosion. Their characterisation is crucial for constraining the properties of the progenitor of…

Exploring the central region of SNR 0540-69.3 with JWST I: 3D morphology

J. Larsson, C. Tegkelidis, C. Fransson +3

The young supernova remnant SNR 0540-69.3 in the Large Magellanic Cloud offers a detailed view of an energetic pulsar-wind nebula interacting with the surrounding ejecta. We presen…

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,…

Spatial Variations and Breaks in the Optical-NIR spectra of the Pulsar and PWN in SNR 0540-69.3

L. Tenhu, J. Larsson, J. Sollerman +4

The supernova remnant SNR 0540-69.3, twin of the Crab Nebula, offers an excellent opportunity to study the continuum emission from a young pulsar and pulsar-wind nebula (PWN). We p…

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…
