blue star

Extremely luminous celestial body

A blue star is an extremely hot, luminous star that appears blue or blue-white due to its high surface temperature.

Blue stars are among the most massive and short-lived stars in the universe.

The term also refers to a blue star-shaped symbol used to mark homes of military service members, displayed in windows during wartime: a blue star banner hung in her window while her son served overseas.
