Plain-language explanations and a rich set of supporting material help students understand the mathematical concepts and techniques of astronomy.Equivalently, LM = 1 LRG, or LRG = 106LM. 106 So in this case the red giant is a million times more luminous than the small M star. Since their temperatures are the same, this difference is due entirely to the larger size of the red giant.
