The hertzsprungrussell diagram abbreviated as hr diagram hr diagram or hrd is a scatter plot of stars showing the relationship between the stars absolute magnitudes or luminosities versus their stellar classifications or effective temperaturesthe diagram was created independently around 1910 by ejnar hertzsprung and henry norris russell and represented a.
Stages of stellar evolution occupy specific regions on the h r diagram and exhibit similar properties. As we said last time the spectral sequence o b a f g k m is a temperature sequence with the hottest stars being of type o surface temperatures 30000 40000 k and the coolest stars being of type m surface. Astronomers also use the historical concept of magnitude as a measure of a stars luminosity.
