Star brightness equation
Webb3 maj 2024 · The relationship between brightness (B) and luminosity (L) is described by B = L 4 π d 2 (1). So we have three variables, brightness, luminosity and distance. So out of … WebbLet the stars be at distances r1 and r2 from the center of mass; clearly we have M1r1 = M2r2 r1 +r2 = a Gm1 a2 = v2 2 r2 Gm2 a2 = v2 1 r1. The first two equations give r1 = M2 M1 +M2 a r2 = M1 M1 +M2 a. Since the stars are always separated by a distance a, star 1 feels a gravitational acceleration ¨r1 = GM2/a2 and star 2 feels an acceleration ...

WebbIf they know the star's brightness and the distance to the star, they can calculate the star's luminosity: [luminosity = brightness x 12.57 x (distance) 2]. Luminosity is also related to … WebbFrom a reference star we calculate the background brightness or light pollution: Reference star magnitude; 1.00 to 25.00 m : Pixel scale of your optic system: Pixel scale = Calculated results: 0.10 to 100.00 arc seconds / pixel : arcsec 2 / pixel: ADU sum from all reference star pixels: Star flux ADU counts : 1.0 to 1000000.0 ADU counts
WebbThe 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 … Webbthere, let’s call it “Star” B, but we will think that the flux of “Star” B is twice that of Star A. Calculate the measured magnitude, m B,of“Star”B. Note, that it is absolutely incorrect to …
WebbSirius, the brightest apparent star in the winter sky,and the Sun have an apparent magnitude difference of about 25. This means that we would need 2.5 25 or about 9 … http://astronomyonline.org/Science/Brightness.asp
WebbIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness (b2 b1) ( b 2 b 1) using this equation: m1 −m2 = 2.5log(b2 b1)orb2 b1 = …
