One can determine the surface temperature of each star (i.e. the temperature of each star's
photosphere) using the full spectrum in the top graph of each panel and Wien's Law:

5. One can determine the surface temperature of each star (i.e. the temperature of each star's photosphere) using the full spectrum in the top graph of each panel and Wien's Law: 2.9x10' T= 2 where T is temperature in Kelvin and Npcak is the wavelength in Ångstroms where the blackbody curve peaks. Determine the surface temperature of each star using the top graph of each panel by following the procedure below: peak a) Trace the underlying blackbody continuum in the top graph of each panel. (This is what the spectrum would look like with no absorption lines-i.e. a perfect blackbody.) b) In the second column of Table 3 write down the wavelength (in Ångstroms) where the blackbody continuum in each panel peaks. If the peak is not shown on the graph, then write down a rough estimate of where you think the curve might peak. c) Use Wien's Law (formula above) to calculate the surface temperature of each panel's star. Record your answer in column 3 of Table 3. Table 3 Peak Wavelength (Angstroms) Panel Surface Temperature (K) 2 13 4.
