Given the spectral classification of a distant giant star, you will use the H-R diagram to estimate its absolute magnitude and luminosity. From the distance modulus formula, you will estimate its distance via spectroscopic parallax. From the spectral type, you will estimate its surface temperature and then use the luminosity formula to estimate the diameter of your giant star.---------------------------------------Distant Nature: Astronomy Exercises 2016 by Stephen Tuttle under license "Creative Commons Attribution Non-Commercial Share Alike".
