Luminosity of megastar Lx/Ls= (Rx/Rs)²(Tx/Ts)^4 x = megastar s = solar L = luminosity R = linier radius T = floor temperature (Ts = 5800 ok), Tx = 25000/5800 = 4.31 Ts Lx = 8² * 4.31^4 Lx = 22,084 Ls Mx - Ms = -2.512 log (Lx/Ls) M is absolute value, with Suns absolute value is 4.seventy 4 Mx = (-2.512 log22,084) + 4.seventy 4 Mx = -6.17
