What else can I help you with?
What do the letters at the bottom axis of the hr diagram represent?
The letters at the bottom axis of the Hertzsprung-Russell (HR) diagram represent the spectral classes of stars, ranging from hotter (O, B) to cooler (G, K, M). Each letter corresponds to a different temperature of the star.
Where is absolute magnitude indicated on the HR diagram?
its located somewhere
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.
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.

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.
Why do most stars characteristics make them appear on the main sequence on the HR diagram?
I assume the different points on the main sequence represent a kind of balance for the case of hydrogen-to-helium fusion.
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.
Difference between class diagram and object diagram with necessary diagram and figure?
Class diagram represent generalized view of system while object diagram represent view of a system at a particular instant.
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.
