What is the general upper mass limit for a star to be classified as low-mass, relative to the Sun?
Answer
Less than about 0.5 to 0.8 times the mass of the Sun
A star is generally classified as low-mass if its mass is less than about 0.5 to 0.8 times the mass of the Sun, though the exact definition can shift based on the evolutionary track.
