Frequently Asked Questions
No, it is a broad category. While often a hot star (like a blue giant), it can also refer to other objects like luminous nebulae or quasars that emit blue light.
It would sound highly technical and unnatural. In everyday talk, people would simply say 'blue star'.
In physics, hotter objects emit light at shorter wavelengths. Blue light has a shorter wavelength than red light, so a blue colour indicates a very high surface temperature.
A 'blue stellar object' is a general descriptive term. A quasar is a specific, extremely luminous type of active galactic nucleus. A quasar may initially be classified as a blue stellar object until its detailed properties are analysed.
A general term in astronomy for any celestial object emitting blue light.

Mnemonic
Think: 'Blue' for hot, 'Stellar' for star-related, 'Object' for thing. BSO = Blazing Space Object.
Conceptual Metaphor
A BLUE STELLAR OBJECT IS A HOT/ENERGETIC ENTITY (due to the association of blue with high temperature in astrophysics).
