The Hertzsprung–Russell diagram, abbreviated as H–R 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 temperatures. The diagram was created … See more In the nineteenth century large-scale photographic spectroscopic surveys of stars were performed at Harvard College Observatory, producing spectral classifications for tens of thousands of stars, culminating … See more There are several forms of the Hertzsprung–Russell diagram, and the nomenclature is not very well defined. All forms share the same general layout: stars of greater … See more Contemplation of the diagram led astronomers to speculate that it might demonstrate stellar evolution, the main suggestion being that stars collapsed from red giants to dwarf stars, then moving down along the line of the main sequence in the course of … See more • Omega Cen H-R animation of a Hertzsprung–Russell diagram created from real Hubble data • JavaHRD an interactive … See more Most of the stars occupy the region in the diagram along the line called the main sequence. During the stage of their lives in which stars are found on the main sequence line, they are fusing hydrogen in their cores.

WebHenry Norris Russell. One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar … WebThe most surprising thing about the H-R diagram was that the stars were not randomly scattered on it, but clustered in certain regions and along certain lines. The band that stretches across the diagram includes 90% of the stars in the night sky. This band is called the main sequence stars.
WebThe Basic H-R Diagram The stars which lie along this nearly straight diagonal line are known as main sequence stars. The main sequence line accounts for about 80% to 90% of the total stellar population. The basic H-R diagram is a temperature vs. luminosity graph.
