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.
What range of the H-R diagram is your Sun placed in because its temperature and absolute magnitude are average?
between the yellow stage color on the digram
If a main sequence star has an apparent magnitude of 5 what is it's spectral type?
It may be just about anything. The apparent magnitude tells us how bright the star looks to us, not how bright it really is. The apparent magnitude (or brightness) depends both on the absolute magnitude (real brightness), but also depends on the star's distance.
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.
What classify a star as a star?
It traces to the Greek astronomer Hipparchus (or the Alexandrian astronomer Ptolemy-references vary). He classed stellar objects on how bright they appeared - the brightest were "magnitude 1", the next brightest were "magnitude 2", on down to "magnitude 6", the faintest he could see. Thus the scale is roughly 2000 years old.
What is a b-r diagram?
A Hertzsprung-Russell (H-R) diagram, also known as a color-magnitude diagram, is a graph that plots stars based on their absolute magnitude (brightness) and spectral type (color). It is a valuable tool for studying the properties and evolutionary stage of stars within a specific population.

What color is the beta cancri and magnitude?
The apparent magnitude is +3.5 and the absolute magnitude is -1.25.
What is plotted on the horizontal axis of an H-R diagram?
If you mean a Hertzsprung-Russell Diagram, which plots stars color, temperature, and absolute magnitude (see related link), then it looks like color and spectral class (temperature) are plotted on horizontal, and Absolute Magnitude/Lumenoscity are plotted on the vertical.
What is the largest star in the hr diagram?
For a long times, it was considered to be VY Canis Majoris, but new studies have reduced its size. The present record is held by UY Scuti at 1708 times the diameter of the Sun. That works out to about 2,250,000,000km.
The H-R diagram shows relationship between a star's absolute magnitude and its?
The H-R diagram (Hertzsprung-Russell diagram) illustrates the relationship between a star's absolute magnitude (luminosity) and its surface temperature (or color). It categorizes stars into different groups such as main sequence stars, giants, and white dwarfs, highlighting their evolutionary stages. The diagram reveals that hotter stars are generally more luminous, while cooler stars tend to be dimmer. This relationship helps astronomers understand stellar evolution and the characteristics of different types of stars.
What does the color of an electromagnetic wave depend on?
It depends on magnitude.
If a main sequence star has an apparent magnitude of 5 what is it's spectral type?
It may be just about anything. The apparent magnitude tells us how bright the star looks to us, not how bright it really is. The apparent magnitude (or brightness) depends both on the absolute magnitude (real brightness), but also depends on the star's distance.
