To which spectral classification range does the star Rigel in Orion belong based on its associated temperature?
Answer
The Blue-White class, registering between 10,000 K and 25,000 K.
Rigel, located in the constellation Orion, serves as a specific example used to illustrate a particular temperature bracket in stellar classification. This star is explicitly mentioned as belonging to the Blue-White category. This class bridges the gap between the absolute hottest Blue stars and the middle-spectrum White stars. The associated surface temperature range for Blue-White stars is defined as being between 10,000 Kelvin and 25,000 Kelvin. Stars in this intense heat category emit the majority of their radiation at the shorter, high-energy end of the spectrum.
