WebLet us consider now an even simpler case: a star which may be described with the equations in which all time derivatives may be neglected, i.e. a star that is in the hydrostatic and thermal equilibria. Now, that we have no time dependence, the stellar structure depends on one space-like variable only, which we may choose to be radius r, or the ... WebThe luminosity of a star is given by the equation L = 4 p R 2 s T 4, Where L is the luminosity in Watts, R is the radius in meters, s is the Stefan-Boltzmann constant (5.67 x 10 -8 Wm -2 K -4 ), and T is the star’s surface temperature in Kelvin. The temperature of a star is related to its b-v magnitude. the analyst podcast cricket
