Superflares from M dwarf hosts drive order-of-magnitude atmospheric chemistry changes in brown dwarf companions, but fast chemical relaxation (under a day) leaves high-resolution emission spectroscopy within hours of a flare as the only plausible, still very challenging, detection route.

Simulations of Flare Chemistry in Brown Dwarf Companions to Active M Dwarfs
Superflares from M dwarf hosts drive order-of-magnitude atmospheric chemistry changes in brown dwarf companions, but fast chemical relaxation (under a day) leaves high-resolution emission spectroscopy within hours of a flare as the only plausible, still very challenging, detection route.
