Diameter of a star calculator

Web1. To calculate the linear diameter of a star, we need only to know its effective temperature, the bolometric correction, and its absolute magnitude. And if, instead of the absolute magnitude, we know the apparent diameter can then calculate the angle. The formula used to determine the size of a star appeared in Article Stellar Masses of Daniel ... WebThe formula for luminosity is as follows: L/L☉ = (R/R☉)2(T/T☉)4. Where, the star luminosity is L. L☉ is the luminosity of the sun and is equal to 3.828 x 10 26 W. Radius is R. T is the temperature of the star in Kelvins. R☉ is the radius of the sun and equal to 695700 km.
