What are the 3 main groups of stars on an hr diagram?
The three main groups of stars on the Hertzsprung-Russell (HR) diagram are main sequence stars, red giants, and white dwarfs. Main sequence stars, which comprise the majority of stars, fuse hydrogen into helium in their cores and are found along a diagonal band from the upper left to the lower right. Red giants, located in the upper right, are evolved stars that have expanded and cooled after exhausting their hydrogen. White dwarfs, found in the lower left, are remnants of stars that have shed their outer layers and are no longer undergoing fusion.
Where is absolute magnitude indicated on the HR diagram?
its located somewhere
What is the location on the HR diagram where most stars lie known as?
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.

Where does a star spend most of its life on an hr diagram?
On the main sequence.
The hr diagram graphs what 2 things?
The temperature and luminosity of stars.
Why is there no neurton stars in the hr diagram?
Of course they are on the HR diagram. They are simply not on the main sequence.
Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.

What chart show is the characteristics of a star?
HR diagram
What are the smallest stars in the HR diagram?
The red dwarves.
What part of the HR diagram are Red supergiant stars in?
Up at the top right. If you look on the Australian Telescope National facility website, their HR diagram shows this clearly.
Why is the hr diagram important to scientist?
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.
Where is absolute magnitude indicated on the HR diagram?
its located somewhere
What types of stars are found on an HR diagram?
All stars.
What is the approximate position of the Sun In the HR diagram?
Slightly to the right of centre on the main sequence. If you look on the Australian Telescope National facility website, their HR diagram shows the position of the sun.
What are the colors of the HR Diagram?
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
What graph shows the relationship of a stars absolute magnitude and its temperature?
Its called an HR diagram or a Hertzsprung-Russell diagram.
