Atlas12 models are computed for stars with 7000 k t e 15000 k. Using the hr diagram determine which has more mass. Consider the hr diagram shown. L l sun.

Considering the hr diagram above which of the listed stars is the brightest. 2 pts draw an hr diagram that shows the location of the main sequence giant branch horizontal branch and white dwarfs. This can be expressed as a ratio of the stars luminosity to that of the sun. Since 1943 the spectrum of this star has served as one of the stable anchor points by which other stars.

Instead of plotting their luminosities which are so large that theyre hard to visualize plot the stars absolute magnitudes. By tradition the absolute visual magnitude runs along the vertical axis going from low luminosity large positive values of magnitude to high luminosity negative values of magnitude when going from bottom to top and the color along the horizontal axis going from blue to red when moving from left to right.
