What measurements would you make (assuming you have the money, time, & equipment) to determine a star’s surface temperature?
For a star with surface temperature 5,100 K, what is the peak frequency of light from the sun?
Write your answer in THz (1012 Hz), to zero decimal places. Take the speed of light to be c=3 x 108 m/s.

What part of the star do these temperatures refer to? Why?arrow_forwardWhat are the largest- and smallest-known values of the mass, luminosity, surface temperature, and diameter of stars (roughly)?arrow_forward
- The spectrum of the Sun has hundreds of strong lines of nonionized iron but only a few, very weak lines of helium. A star of spectral type B has very strong lines of helium but very weak iron lines. Do these differences mean that the Sun contains more iron and less helium than the B star? Explain.arrow_forwardThe luminosity of a star is 6.6 x 1031 W and the peak wavelength in its spectrum is 4.6 x 10-7 m. Calculate the surface area of that star.
