If a stable star exceeds 50,000 Kelvin on its surface, what type of star is it likely to be?
Answer
It is likely an extremely hot, transient star only briefly reaching that temperature.
O-type stars typically feature surface temperatures above 30,000 Kelvin, but stable stars rarely exceed 50,000 Kelvin, although the most luminous and hottest may briefly reach up to 100,000 Kelvin.
