Important sections of it include the Henyey and Hayashi tracks as well as a portion known as the Turnoff Point.
One of its namesakes would work with Hermann Vogt in developing a theorem that linked chemical composition and mass. Important sections of it include the Henyey and Hayashi tracks as well as a portion known as the Turnoff Point. It contains a portion known as the instability strip that contains RR Lyrae and Cepheid variables. Its bottom axis contains a color index and its top axis contains classes from O to M which cover a temperature range from 3,000 Kelvin to 30,000 Kelvin. It contains a central area known as the main sequence that falls below super giants and above white dwarves. FTP, name this diagram used in astronomy that compares stellar classification, color, luminosity and temperature.
