Question 19
The following graph shows spectral flux density as a function of wavelength for the 2 stars in a binary system. Assume that the stars are young and are comprised only of Hydrogen and a small amount of Helium. Moreover, assume that the stars can be treated as black bodies. Take Wien’s Displacement Constant to be 2.8978 mm K (The origin of the graph corresponds to zeroes for both wavelength and spectral flux density). What are the surface temperatures of the 2 stars?
