Question

1. We measure the black body spectrum of a star in a star cluster and find that it has a surface temperature of 10,000 K. a. Assuming the star is a Main Sequence star, what is the luminosity in Watts? The sun's luminosity is 3.91 x 10^26 Watts. b. If the measured intensity of the star is 8.1 x 10^-14 Watts per square meter (W/m^2), how far away is the star in light years?
