Hey.. need some help in solving this problem:
Q) The luminosity of Polaris is 10,000 times the luminosity of the sun. The surface temperature of Polaris is about 5800 kelvins. Using k=33,640,000 find how the diameter of polaris compares with the diameter of the sun. ( Equation: D= (K)(sqrt of L ) / (T)^2
Dp/Ds = ( k(sqrt of Lp ) / (Tp)^2 ) / ( k(sqrt of Ls) / (Ts)^2 )
= ( sqrt of 10,000Ls ) / (5800)^2 / ( sqrt of Ls ) / (Ts)^2)
Now I'm stuck.. Not sure what this problem is leading to.. i don't know the value of Ts and hence am not going to get an answer.. Any help is much appreciated..
