SN 2023fyq is the first Type Ibn supernova with a directly detected hot luminous progenitor consistent with a low-mass helium star in a binary system, based on pre-explosion imaging, disappearance confirmation, and multi-wavelength environmental analysis.

UNVERDICTED 3representative citing papers
First radio observations of SN 2023fyq detect a dense circumstellar shell with mass-loss rate ~0.004 solar masses per year ejected 0.7-3 years before explosion, consistent with a merger origin.
Late-time JWST spectra of SN 2023xgo detect cool silicate or carbonaceous dust masses of order 0.01-0.03 solar masses plus narrow He I emission indicating ongoing circumstellar interaction at +377 days.
