Rare blue optical transient points to possible new class of cosmic explosion
Astronomers have identified a rare, fast-rising blue optical transient (FBOT) designated AT2019ijn in the center of a dwarf galaxy. The event, characterized by bright radio emissions, may represent a new class of cosmic explosion involving a black hole destroying a star.
Why it matters
The discovery of unique transient events helps astronomers refine models of stellar death and the behavior of intermediate-mass black holes.
