Brightness vs luminosity
Web10 Apr 2024 · Luminosity is the amount of energy that a star pumps out every second. The lower the absolute magnitude of a star is, the more luminous the star is. For instance, Sirius the star's absolute magnitude is 1.45, and its luminosity is 25.82. Compare it to Tarazed, which has an absolute magnitude of -3.03 and a Luminosity of 2948.48. WebSince the difference is 2.5 times for each “step” of magnitude, the total difference in brightness is 2.5 × 2.5 = 6.25 times. Here are a few rules of thumb that might help …
