2. Thermal Spectra and the HR Diagram Four stars have their temperature and luminosity plotted on the HR diagram below. On the next page, for each star, identify the star's temperature and draw its continuous thermal spectrum to accurately represent its temperature and luminosity relative to the other stars. Luminosity (L.,,) 40,000 20,000 10,000 5,000 2,500 Temperature (K) Intensity Intensity Star A Star B = T= 2 0 c 2 E VIBGYOR VIBGYOR Wavelength Wavelength Starc StarD = T= 2 0 c 2 = VIBGYOR VIBGYOR Wavelength Wavelength
