WebIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works. WebTo determine the relative sizes of the two stars, we take the ratio of the corresponding luminosities: L Sirius L companion = ( A Sirius × F Sirius) ( A companion × F companion) = A Sirius A companion = 4 π R 2 Sirius 4 π R 2 companion = R 2 Sirius R 2 companion L Sirius L companion = 8200 = R 2 Sirius R 2 companion.
