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…
