The Hertzsprung-Russell diagram shows absolute magnitute or brightness against it's colour (which is an indication of temperature) . This shows the main sequence, which describes the typical life of a star.

The amount of light we receive from a star - other things being equal - is inversely proportional to the square of the distance. For example, from a star that is ten times as far from us as another star (of the same type), we will only receive 1/100 of the light that we receive from the closer star.

The "actual" brightness of the star is called "absolute magnitude". It is calculated as if all stars were at the same distance, so that we can compare stars directly. The "apparent magnitude" of the star is how bright it appears in our own night sky.

Two stars can have the same apparent magnitude even though one star is small, dim and close, while the other star is huge, bright and distant.

generally the hotter the star the more bright it will be generally the hotter the star the more bright it will be

Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.

Hotter stars appear brighter, and cooler stars appear dimmer

### In main-sequence star how does brightness relate to temperature?

The brightness is very similar to the temperature, the brightness relies on the temperature

### Who Discovered The Relationship Between The Stars Temperatures?

The relationship between a star's temperature and brightness was discovered independently around 1910 by Ejnar Hertzsprung and Henry Norris Russell. The relationship between these to parameters is depicted in a Hertzsprung-Russell diagram or H-R diagram.

### Who discovered the relationship betweens a star's temperature and its brightness?

Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.

### What relationship is shown on the HR diagram?

The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).

### Does the stars mass have anything to do with the stars brightness?

the brightness of a star is dependant on its temperature and radius. however, while a star is burning hydrogen into helium (which all stars do for most of their lifespan and it's usually this kind of object we mean when we say "star") a correlation does exist between the mass of the star and its luminosity (brightness)

### What is difference between apparent brightness and absolute brightness?

Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.

### What location on the graph best represents a star with average brightness and temperature?

Stars' brightness and temperature are typically represented on a Hertzsprung-Russell (H-R) diagram. An average star like the Sun would be located on the &quot;Main Sequence&quot; portion of the graph, where brightness increases as temperature increases.
