What is the general range for the absolute magnitude of Bright Giants?
Answer
Between -3 and -5
The intrinsic brightness of stars, quantified by absolute magnitude, is a key factor in classifying bright giants. These stars fall within a specific range, generally possessing an absolute magnitude between -3 and -5. This range corresponds to a collective luminosity equivalent to shining with the light of hundreds to thousands of Suns. For instance, a specific value within this range, like an absolute magnitude of -4, indicates a star is approximately 630 times brighter than the Sun, illustrating the substantial increase in light output achieved during this evolutionary phase.
