WebThis is exactly what we found earlier when we examined the mass-luminosity relation ( Figure 18.9 ). We observed that 90% of all stars seem to follow the relationship; these are the 90% of all stars that lie on the main sequence in our H–R diagram. Our models and our observations agree. WebThe answer turns out to be about 2.5, which is the fifth root of 100. This means that a magnitude 1.0 star and a magnitude 2.0 star differ in brightness by a factor of about 2.5. … iowa bankruptcy attorney cheap
