Looking for the tell-tale photometry of red supergiants before they go supernova

[gary]

In a 13 October 2022 article published in the Monthly Notices of the Royal
Astronomical Society, Davies et. al. make a prediction that red
supergiants (RSG) will undergo "dramatic photometric variability in the
optical and infrared in the weeks-to-months before core-collapse" and
exploding as a type II-P supernova.
