The temperature is displayed along the horizontal axis while the vertical axis is the star's absolute magnitude. So the HR diagram is a scatter diagram relating temperature and brightness, and eah star occupies one point.
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
Of course they are on the HR diagram. They are simply not on the main sequence.
Hertzsprung-Russell (HR) diagram classifies stars based on their luminosity (brightness) and temperature. This diagram allows astronomers to categorize stars into main sequence, giants, supergiants, white dwarfs, and other classes based on their positions in the diagram. It provides insights into the life cycle and evolutionary stage of stars.

The temperature and luminosity of stars.
It shows certain key characteristics (brightness, and temperature) of stars.
The HR diagram contains only stars - so everywhere.
The location on the Hertzsprung-Russell (HR) diagram where most stars lie is known as the main sequence. The HR diagram is a plot of stellar luminosity against surface temperature. The main sequence is a prominent band that extends diagonally across the HR diagram from high temperature and high luminosity to low temperature and low luminosity. The majority of stars, approximately 90% of all stars, are situated along the main sequence on the HR diagram. These stars are often referred to as main-sequence stars. They exhibit a smooth relationship between surface temperature and luminosity, with varying sizes and masses but sharing this common characteristic of lying on the diagonal band from the upper left to the lower right of the HR diagram.

The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
Its called an HR diagram or a Hertzsprung-Russell diagram.
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.
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.
A blue dwarf star would have high temperature and low luminosity in the Hertzsprung-Russell (HR) diagram. Blue dwarf stars are in the lower left corner of the diagram, characterized by their high surface temperature and faint luminosity compared to other stars of similar temperature.
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.
Of course they are on the HR diagram. They are simply not on the main sequence.
