Solve this with respect to r gives radius: r = (A / 4π)^0,5 = (3,25 * 10^23 / 4π)^0,5 = 1,61 * 10^11 m. The radius of the sun: 6,96 * 10^8 m. Solar radius = (1,61 * 10^11) / (6,96 * 10^8) = 231,06Rsun. The Rigel radius is 231 times the radius of the sun. However, Wikipedia says 78.
WebbIf 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.
