White dwarfs.
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
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".

On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.
evolving into a later stage. For example, a G2 star going into a red giant (M type)
Of course they are on the HR diagram. They are simply not on the main sequence.
The HR diagram contains only stars - so everywhere.
The Sun is located on the main sequence of the H-R diagram, which is where stars like the Sun reside for most of their lifetime. It falls in the middle of the main sequence, representing a stable phase of hydrogen fusion in its core.
To read an HR diagram, look at the stars' luminosity on the vertical axis and their temperature on the horizontal axis. The main sequence represents stars in stable fusion. Interpret data by noting a star's position on the diagram to determine its temperature, size, and stage of evolution.

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.
