On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
Who were Enjar Hertzsprung and Henry Russell?
Enjar Hertzsprung lived in 1873-1967 and Henry Russell lived in 1877-1957. They were scientists who worked separtely. They found the same answer about the temperature and color of stars. The diagram that they made is called the Hertzsprung-Russell diargram. It shows the connection between surface temperature and color.The discoverers of the famous Hertzsprung-Russel diagram (HR diagram), which turned out to be an important tool for the analysis of stars.
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).
The region of the Hertzsprung-Russell diagram with the most stars is the what?
The main sequence - the region across the middle of the diagram.
What is anH-R diagram?
That's short for Hertzsprung-Russel diagram. It is a diagram in which the total luminosity versus color (and therefore temperature) of many stars is plotted.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
What is a graph that shows relationship between a stars magnitude and temperature?
Its an Hertzsprung-Russel (H-R) diagram.
As shown in a Hertzsprung-Russel diagram the main-sequence stars are defined according to their?
Absolute magnitude and surface temperature
By studying the you can learn a great deal about the sizes colors and temperatures of stars?
By studying the Hertzsprung-Russel diagram we can learn a great deal about the sizes colors and temperatures of stars
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
What are main group of star?
This may refer to the main sequence - stars that are on the main curve in the Hertzsprung-Russel diagram. Those are basically the stars that use fusion to convert protium into helium-4.
What is the diagram that classifies stars on a temperature-luminosity graph?
Hertzsprung-Russell diagrams are also referred to by the abbreviation H-R diagram or HRD. The diagram was created circa 1910 by Ejnar Hertzsprung and Henry Norris Russell and represents a major step towards an understanding of stellar evolution or "the lives of stars".
What is the main sequence phase of a star?
The main sequence phase means that, if you plot an H-R (Hertzsprung-Russel) diagram, it is in the so-called "main sequence", the area in the graph where you find the majority of stars. Those are the stars that currently fuse hydrogen into helium.

What relationship is shown on the HR diagram?
The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).
