Introduction to the HR Diagram
... The Y-axis is the total energy output of the star, called the Luminosity. The luminosity of stars is measured in units of the luminosity of the Sun or one solar luminosity. Thus a star that has a luminosity of 10 solar luminosities outputs 10 times more energy than the sun. An alternative way of m ...
