Structure of the H-R Diagram

Description
Structure of the H-R Diagram
(a) Data taken by the Hipparcos satellite placed 41,453 stars more precisely on the H-R diagram than any previous observations. This figure shows the overall structure of the H-R diagram. The thickness of the main sequence is due in large part to stars of
different ages turning off the main sequence at different places, as shown in (b).
