Who discovered star life cycles?
The Herzprung - Russell diagram depicts the life of stars, and their luminosity and size. You will be able to look it up in wikipedia.org for example.
What is the name of the person that discovered the relationship between a star's temperature and its brightness?
The two people who discovered the relationship between a star's temperature and its brightness were Ejnar Hertzsrung and H.N. Russell. The two men were working from research that had been done by Ludwig Boltzmann and Joseph Stefan.
What may happen to massive stars at the end of their cycles?
Most stars usually die out
What are the very bright starts in the upper right of an h-r diagram called?
Hot stars are found in the left hand side of the diagram, cool stars the right, bright stars at the top, and lastly the faint stars are located at the bottom.
What is a H-R diagram and what two characteristics of stars are compared on it?
It is a diagram on which stars are plotted according to their absolute magnitudes (or luminosities) against their stellar classifications (or effective temperatures).
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.
Why isn't altazimuth system a useful system for plotting positions of stars?
Because the Earth is spinning at a rate of 15 degrees per hour.
Why is the HR diagram useful to astronomers?
It can be used to determine a Stars lifetime, its different stages.
when was the H and R diagram created and how?
The Hertzsprung-Russell diagram, or H-R diagram, was created in 1911 by Ejnar Hertzsprung and Henry Norris Russell. They plotted the luminosity of stars against their surface temperature to classify and study stellar populations. This diagram revolutionized our understanding of stars and their life cycles.

Where are stars on the hr diagram?
The HR diagram contains only stars - so everywhere.
What is the name of the person that discovered the relationship between a star's temperature and its brightness?
The two people who discovered the relationship between a star's temperature and its brightness were Ejnar Hertzsrung and H.N. Russell. The two men were working from research that had been done by Ludwig Boltzmann and Joseph Stefan.
What is the brightest star on the H-R diagram?
The "supergiant" stars are the brightest stars on the H-R diagram.
What may happen to massive stars at the end of their cycles?
Most stars usually die out
Do all-stars have the same sunspot cycles?
Not necessarily
What determines the life cycles of stars?
Mainly their mass.
What types of stars are found on an HR diagram?
All stars.
