Horizontal Axis: Temperature in Kelvins (Hottest to coolest)
Vertical Axis: Luminosity, absolute magnitude, or solar radius
A Hertzsprung-Russell diagram or H-R diagram.
Its an Hertzsprung-Russel (H-R) diagram.
The answer to this question is Hertzsprung-Russell diagram
That is called the HR diagram (Hertzsprung Russell) and the temperature is along the horizontal axis while the vertical axis is the star's absolute magnitude. Each star has a fixed point in this diagram, and it shows that most stars belong in a broad band on the left called the Main Sequence.
The Hertzsprung-Russell diagram (H-R diagram) is a graph of stars showing the stars' luminosities or absolute magnitude versus their spectral type which is related to their effective temperature.
The difference between a graph and a diagram is as follows: a diagram is a chart which shows a drawing and a graph is a graph with lines or bars indicating something specific in numbers.
The difference between graph and diagram :- Diagram 1) Diagram can be drawn on plain paper and any sort of paper. 2) Diagram is more effective and impressive. 3) Diagram have everlasting effect. 4) Diagram cannot be used as median, mode etc. 5) Diagram can be represented as an approximate idea. Graph 1) Graph can be drawn only on plain paper. 2) Graph is not more effective and impressive. 3) Graph don't have everlasting effect. 4) Graph can be used as median, mode etc. 5) Graph cannot be represented as an approximate idea.
