What type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
Why is absolute magnitude stars used in the HR diagram?
The equation for the magnitude of a star is; M=m-5log(d/10) where:M - Absolute magnitude (The brightness of a star viewed 10 parsecs away)m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc)
Explain why size is the only factor that determines the stars absolute magnitude?
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
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 happens to the absolute magnitude of a star as one moves up the vertical axis?
The absolute magnitude is referred to a constant, standard distance, so it doesn't change. But the apparent visual brightness increases (magnitude number decreases), because as you climb the vertical axis, you obviously move closer to the star.
What graph shows the relationship of a stars absolute magnitude and its temperature?
Its called an HR diagram or a Hertzsprung-Russell diagram.
As shown in a Hertzsprung-Russel diagram the main-sequence stars are defined according to their?
Absolute magnitude and surface temperature
As shown in a H-R diagram the main-sequence stars are defined according to their?
They are defined by their absolute magnitude and surface temperature.
What are the two ways you can classify stars?
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
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 type of relationship is shown on a HR diagram?
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
What is a graph that shows the relatonship between stars surface temperature and its absolute magnitude?
That is called the Hertzsprung-Russell or HR diagram and each star occupies a point. The horizontal axis is temperature and the vertical axis is the absolute magnitude.
What is the absolute magnitude of the constellation scorpius?
Constellations don't have an absolute magnitude. That is a property of individual stars.
What two caracteristics of a star are plotted on the Hertzsprung Russell diagram?
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
Why is absolute magnitude stars used in the HR diagram?
The equation for the magnitude of a star is; M=m-5log(d/10) where:M - Absolute magnitude (The brightness of a star viewed 10 parsecs away)m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc)
How can stars be classified using the hertz sprung Russell diagram?
On the HR diagram each star occupies a single point, depending on its surface temperature (horizontal) and its absolute magnitude (vertical).
What does and H-R diagram relate a star's temperature to?
The Hertzsprung-Russell diagram (H-R diagram) shows the relationship between absolute magnitude, luminosity, classification, and effective temperature of stars. The diagram as originally conceived displayed the spectral type (effectively the surface temperature) of stars on the horizontal axis and the absolute magnitude (their intrinsic brightness) on the vertical axis.
