White Dwarfs

Using the H-R diagram below, compare the following properties of a white dwarf to those of a main sequence star such as our Sun. You must choose one value for each question.

An H-R Diagram, also know as the Hertzsprung-Russell diagram, is of great importance in the study of stellar evolution. It is a two-dimensional graph that demonstrates the correlation between the spectral type, temperature and luminosity of stars. It shows that 90% of stars lie along a diagonal band known as the main sequence. Remaining stars also form their own individual bands in different spectral type areas of the graph.
