As you can see from the Group 1 stars, the cooler or hotter a star is, the brighter it will be.  Group 2 and Group 3 stars do not follow this pattern.  Hence, there must be something besides temperature that can affect how bright a star is. Why would their brightness not be strictly related to their temperature? Consider what you know about the differences between stars in Groups 2 & 3 from notes, etc.*1 pointBrightness must be related to sizeBrightness must be most related to compositionBrightness must be only related to temperatureBrightness must have some other random causeBackSubmitClear form
