I love words that come from Astrophysics. A new one I learned today is "mergerburst". For that cinematic feel, make sure you pronounce it with an evil tone and a malevolent face, because a mergerburst is a highly-destructive event on a planetary scale.
This post is specifically about a BD-Planet mergerburst, the destruction of a planet by a brown dwarf (BD). When a massive planet approaches a brown dwarf, the poor planet will be tidally destroyed or shredded as it "merges" with a much-denser brown dwarf. The mayhem will form a luminous accretion disk around the brown dwarf that will stay for around a few days, which should be observable, distinct, and identifiable from other mergerbursts such as Star−Planet Mergerbursts, and Planet−Planet Mergerbursts.
Factoid: The existence of Brown dwarfs (BD) were predicted in 1963, and was termed as "black dwarfs" back then.
