You need to know the luminosity and temperature of star in order to plot it on the HR diagram.
To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.
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 two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.
H-R diagrams are used to plot brightness against size and spectrum of a star. For eg, The sun is a medium sized star or a G type star with luminosity showed by surface temperature of 5, 500 degrees centigrade.
It would be beneficial to watch the first movie of the trilogy, but it is not necessarily required. You don't need to have watched the first movie to understand the basic plot.
The hottest type of star on the Hertzsprung-Russell (H-R) diagram is typically a blue star, which falls in the top left portion of the diagram. These stars are usually massive and have high surface temperatures, leading to their blue coloration and positioning on the diagram.
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.
Star A has a higher temperature than star B. In the H-R diagram, stars to the left are cooler and stars to the right are hotter.
The numbers are your ratings
