Rigel's place at top center on the Hertzsprung–Russell diagram Rigel is a blue supergiant that has exhausted the hydrogen fuel in its core, expanded and cooled as it moved away from the main sequence across the upper part of the Hertzsprung–Russell diagram.
The Hertzsprung Russell Diagram. The most famous diagram in astronomy is the Hertzsprung Russell diagram. This diagram is a plot of luminosity (absolute magnitude) against the colour of the stars ranging from the high temperature blue white stars on the left side of the diagram to the low temperature red stars on the right side.
In an H R diagram the luminosity or energy output of a star is plotted on the vertical axis. This can be expressed as a ratio of the star's luminosity to that of the Sun; L * L sun. Astronomers also use the historical concept of magnitude as a measure of a star's luminosity.
hertzsprung russell diagram this hertzsprung russell diagram shows a group of stars in various stages of their evolution by far the most prominent feature is the main sequence which runs from the upper left hot luminous stars to the bottom right cool faint stars of the diagram the giant branch is also well populated and there are many white dwarfs
The Hertzsprung Russell diagram, or simply the H R diagram, plots star color along the horizontal axis and luminosity along the vertical axis. To make the chart fit on a single page, we actually plot the log 10 of the luminosity. [If you are not familiar with the idea of log 10, don't worry about it.
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 Hertzsprung, plotted the absolute magnitude of stars against their colour (hence effective temperature).
A Simple H R Diagram. Once you know the luminosity and temperature (or color) of a star, you can plot the star as a point on the H R diagram. Plot the luminosity on the y axis with brighter stars going toward the top.
THE HR DIAGRAM THE MOST FAMOUS DIAGRAM in ASTRONOMY Mike Luciuk 1.INTRODUCTION Late in the nineteenth century, astronomers had tools that revealed a great deal about stars. By that time, advances in telescope design and photographic emulsions were becoming mature.
