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.
