Apparent magnitude was first documented by the Greek scientist and mathematician Hipparchus. In about 130 B.C., Hipparchus recorded how bright the stars were to each other when viewing them in the night sky. Hipparchus gave the brightest stars in the sky a value of '1'. The next brightest ...
Parallax, Apparent Magnitude and Absolute Magnitude We have seen that the flux F and luminosity L of a star (or any other light source) are related via the equation: F D L 2 4π = Trigonometric Parallax Hence, to determine the luminosity of a star from its flux, we also need to know...
