What is the rleationship between luminosity and tempeature for stars on the main sequence?
On a logarithmic scale for luminosity, it is quite close to a negative linear relationship.
How do you determine a stars luminosity?
To determine a star's luminosity is from size and temperature.
What is the general relationship between the temperature and the luminosity of main sequence stars?
The scatter plot of the relationship between a star's temperature and luminosity is represented by the Hertzsprung-Russell diagram. In a standard H-R diagram the horizontal axis shows the [surface] temperature, increasing from right to left, while the vertical axis shows luminosity increasing from bottom to top. When both axis are on a logarithmic scale, the main sequence stars from a diagonal belt stretching from top right (very hot and very luminous) to bottom left (not so hot and not so luminous).
What is the use of Hertzsprung Russell diagram?
It shows the relationship between stars luminosity versus their classifications and effective temperatures
Does An HR diagram plots a stars luminosity and surface temperature?
Yes.
Which statement describes the general relationship between temperature and luminosity of main sequence stars?
as surface temperature increases, luminosity increases
What describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.
What correctly describes the relationship between the luminosity of two stars that have the same radius?
The star that is hotter will have a higher luminosity.

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 the use of Hertzsprung Russell diagram?
It shows the relationship between stars luminosity versus their classifications and effective temperatures
Relationship between stars distance to earth and luminosity?
Generally speaking, the apparent luminosity would be an inverse square relationship, which is to say, if the same star was at twice the distance, a quarter of the light would be reaching the observer. But absolute luminosity can of course vary without regard to distance from Earth - dim stars can be close, or bright stars distant, or vice-versa.
The hr diagram graphs what 2 things?
The temperature and luminosity of stars.
Does An HR diagram plots a stars luminosity and surface temperature?
Yes.
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.
