Hr Diagram Sun

Hr Diagram Sun. In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. Several of the brightest stars are identified by name.

Are all stars suns? - Quora (Bessie Harrison)

The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed How is the sun similar to other stars? The surface temperature, color, luminosity, and radius of stars can all be deduced from their location on the H-R diagram. Luminosity is the total energy that a star produces in one second.

It is an important astronomical tool for understanding how stars evolve over time.

Einar Hertzsprung was a Danish The basic H-R diagram is a temperature vs. luminosity graph.

It is something of a "family portrait." It shows stars of different ages and in different stages, all at the same time.. It shows the relation between stars' luminosity (that is, how bright they are) and their temperature (how hot they are). In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis.
