JWST nebular spectra detect cooling ~400 K carbonaceous dust emission in normal SN Ia 2023qov at +276 and +363 days, modeled as pre-existing circumstellar dust with mass ~10^{-4} M_sun located within ~1 light year.

The DECam Shadow Survey has detected variable LBV eruptions in AT2017des with peaks brightening by ~0.05 mag per year, reaching luminosities similar to extreme SN impostors.
SN 2020aze displays early He II emission from ejecta-CSM interaction, a steep V-band decline, and semi-analytical modeling yields a ~14 solar-mass red supergiant progenitor with ~12 solar-mass ejecta and 1.5e51 erg explosion energy.
SN 2025ngs is a short-plateau supernova resembling SN 1998S but fainter, with spectral evidence for interaction with a proximate ring-like circumstellar medium around a supergiant progenitor.

Early interaction signatures and an extended plateau phase in Type II SN 2020aze
SN 2020aze displays early He II emission from ejecta-CSM interaction, a steep V-band decline, and semi-analytical modeling yields a ~14 solar-mass red supergiant progenitor with ~12 solar-mass ejecta and 1.5e51 erg explosion energy.

The Eye of Sauron in SN 2025ngs: a Short-plateau Cousin of SN 1998S with Evidence for a Ring-like Circumstellar Medium
SN 2025ngs is a short-plateau supernova resembling SN 1998S but fainter, with spectral evidence for interaction with a proximate ring-like circumstellar medium around a supergiant progenitor.
