Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
the relationship between a star's luminosity, temperature, absolute magnitude, and spectral type.
There is no stationary star anywhere in the universe.
That would be the Dog Star: Sirius.
Many planets around each star reflect the star's light. For example think about Earth's orbit around the sun, a big star

A main-sequence star is one that is along a curve where the majority of stars are located, when plotted in an H-R diagram. It is a star that gets its energy from fusing hydrogen-1 into helium-4.
It means that the two measurements that are plotted on the H-R diagram - its luminosity and its spectral type (equivalent to its temperature) - change.
i don't know about the hr diagram but the brightest star known is r136a1
Star clusters are collections of same-age stars that remain intact for billions of years. When plotted on a H-R diagram, a cutoff point of stars leaving the main sequence and massive stars further evolved are shown, confirming the theory of stellar evolution.
The Star-Delta control circuit diagram shows the delta contact and the main contact.
I found my diagram at autozone.com
PLC logic is a digital computer used to automate electromechanical processes. The Star delta diagram is a diagram for a simple circuit that has the capabilities of starting a high horse power motor. A star delta diagram can be drawn in PLC Logic.
That is short for Hertzsprung-Russell diagram. It is a diagram in which the brightness of stars is plotted against their surface temperature (which can be deduced from their color). It turns out that most stars (basically, the ones that get their energy from fusion of hydrogen to helium) are on, or close to, one particular curve in the diagram - the so-called "main sequence".
You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
