A dusty veil shading Betelgeuse during its Great Dimming

M Montargès, E Cannon, E Lagadec, A de Koter… - Nature, 2021 - nature.com
Red supergiants are the most common final evolutionary stage of stars that have initial

Axion-sourced fireballs from supernovae

M Diamond, DFG Fiorillo, G Marques-Tavares… - Physical Review D, 2023 - APS
New feebly interacting particles would emerge from a supernova core with 100-MeV-range
energies and produce γ rays by subsequent decays. These would contribute to the diffuse …
