Does the H-R diagram classify stars by the amount of heat they create?
The Hertzsprung-Russell diagram (H-R diagram) is a graph of stars showing the stars' luminosities or absolute magnitude versus their spectral type which is related to their effective temperature.
What does Hertzsprung-Russell diagram graph?
The Hertzsprung-Russell diagram graphs stars' luminosity (brightness) against their surface temperature (color or spectral type). This diagram helps astronomers study the relationships between a star's temperature, size, age, and evolutionary stage.
Does An HR diagram plots a stars luminosity and surface temperature?
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
A graph used by scientists that shows stars grouped by size is called the?
Hertzsprung-Russell diagram. This diagram plots a star's luminosity against its temperature (or color), allowing scientists to classify stars by size, brightness, and lifecycle stage.
What is a graph that shows relationship between a stars magnitude and temperature?
The Hertzsprung-Russell (HR) diagram is a graph that shows the relationship between a star's magnitude (luminosity) and temperature. It plots stars based on their color (temperature) and brightness (magnitude), allowing astronomers to classify stars and understand their evolutionary stage.
Does the H-R diagram classify stars by the amount of heat they create?
The Hertzsprung-Russell diagram (H-R diagram) is a graph of stars showing the stars' luminosities or absolute magnitude versus their spectral type which is related to their effective temperature.
What diagram graphs types of stars?
I believe you are thinking of a Hertzsprung-Russell diagram, but this denotes the relationship between a stars luminosity and it's spectral class.It has nothing to do with the life cycle of a star.See related questions for more information
A graph that plots luminosity vs. temperature of stars?
A graph that plots luminosity versus temperature of stars is known as the Hertzsprung-Russell diagram (H-R diagram). In this plot, temperature is typically displayed on the horizontal axis (decreasing from left to right), while luminosity is shown on the vertical axis. The H-R diagram reveals distinct groups of stars, such as main sequence stars, giants, and supergiants, providing insights into their evolutionary stages. This relationship helps astronomers understand stellar characteristics and the life cycles of stars.

What is a graph that shows relationship between a stars magnitude and temperature?
The Hertzsprung-Russell (HR) diagram is a graph that shows the relationship between a star's magnitude (luminosity) and temperature. It plots stars based on their color (temperature) and brightness (magnitude), allowing astronomers to classify stars and understand their evolutionary stage.
Where would a black hole be located on an h r diagram?
A Hertzsprung-Russell diagram is a scatter graph that can be used to plot the relationship between the absolute magnitude (i.e. luminosity) of a star versus it's spectral type / classification and effective temperature. Since a black hole does not have an absolute magnitude, spectral type, or an effective temperature, it cannot be located on an H-R diagram.
What is a H-R diagram?
The Hertzsprung--Russell diagram (or H-R diagram) is a scatter graph of stars showing the relationship between the stars' absolute magnitudes or luminosity versus their spectral types or classifications and effective temperatures. See related link for a pictorial
What variables are on the H-R diagram?
The Hertzsprung-Russell diagram is a scatter graph of known stars. It shows the absolute magnitudes (actual brightness at a set distance) versus the spectral type or classification (which is effectively what their temperature is). Stars, when plotted onto this graph, tend to fall into set patterns. The position of a star within a pattern (or sequence) can give further information, such as how old the star is.
What is an HR diagram and what does it mean to the stars?
A HR diagram(abbreviation of Hertzsprung Russel diagram) is a graph of stars' surface temperatures(x axis) versus their luminosities(y axis). Basically, what we do is observe a lot of stars, find each star's temperature and luminosity and put them all there on the graph. This graph is important in understanding stellar evolution due to a theorem called ergodic theorem. Let us see how. When a star is born, it has a particular luminosity and temperature. As it lives its life, it's luminosity and temperature keeps changing, and finally it finishes it life. Basically, what I mean is that you take a star when it's born, find its temperature and luminosity, put that on a graph that reads luminosity versus temperature for y and x axis respectively, wait a few million years, see the star again, find it's then temperature and luminosity, put that on that graph, and keep doing it till the star dies. What you get then is a graph that tells you how the star's luminosity and temperature changed as it lived it's life. With luminosity and temperature, you can calculate all other stuff about the star and write down it's biography! Do that with all stars, and you get loads of biographies of different stars, and you become a master of stellar evolution! But wait, there is an issue here...a star typically lives it's life in the order of a billion years. We humans evolved one million years back, we discovered telescopes four hundred years back, and a typical human lives a hundred years, how will we understand stars with such little time?! The answer is HR diagram!! Now back to ergodic theorem, it says that seeing a thousand stars as they appear to us now and finding their temperature and luminosity and then putting it on HR graph is same as following a star all it's life! Essentially a shortcut to understanding stars! That's the big advantage of HR diagram in studying stars... of course, the focus of my answer was the importance of ergodicity in studying stars but not explaining in detail the concept of ergodicity. That you can find in any statistical mechanics text book or maybe I can explain that somewhere in answers.com soon! Cheers, hope my answer helped!:)
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".
