Question

Two stars have the same radius but have very different temperatures. the red star has a surface temperature of 3,000 k and the blue star has a surface temperature of 156,100 k. by what factor is the blue star more luminous compared to the red star

Answer 1

I would say that insofar as the two stars temperatures are presumably closely related to their luminosity, that the blue star at 156,100 k compared to 3000k for the red star then the blue star has a luminosity of 52 times that of the red star.
