## Homework Statement

Some values for the Sun are, bolometric luminosity Lbol = 3.83 x 10^26 W, bolometric correction = –0.07, and radius = 6.96 x 105 km.

Calculate the visual luminosity, LV, of the Sun and the flux, FV, radiated into space by the solar surface.

## Homework Equations

M

_{1}-M

_{2}=-2.5 log (F

_{1}/F

_{2})

## The Attempt at a Solution

I have thought of several ways to do this..first way is to use bolometric luminosity and radius to calculate bolometric magnitude using formula M=-2.5 log (F). Since I know bolometric correction, I can find M

_{v}, and then use the same formula to find visual flux, which in turn, find visual luminosity. Or could I just do it with M

_{1}-M

_{2}=-2.5 log (Luminosity

_{1}/Luminosity

_{2}). Actually...wait...couldn't i just use BC= M1-M2=-2.5 log (F

_{1}/F

_{2})..Find the flux (F1) and from there get my luminosity?
