What happens to brightness as surface temperature of the main sequence stars increase?
The hotter the star, the brighter. Ex: A stove
Are main sequence stars hotter or cooler than the sun?
They are both hotter and cooler because the main sequence contains a lot of stars including the Sun. The main sequence is a region on a Hertzsprung-Russell diagram which plots stars on a graph of brightness against surface temperature. Each star is a point on the diagram because it has one value of brightness and one of temperature. All the main-sequence stars lie on or near a line drawn from top left to lower right. The Sun is about halfway along the main sequence.
Compare and contrast the sun with other stars on the hr diagram?
The sun is closer to Earth than any of the other stars. Light from the sun takes 8 minutes to reach Earth, but light from others stars take years to reach Earth. They both are giant balls of hot gas.
Which main-sequence stars are brightest?
The most massive main sequence stars are the brightest, (O main sequence star on Hertzsprung-Russel Diagram). Main sequence stars obey a mass-luminosity relation. On the H-R diagram the vertical axis is the brightness. So the stars along the top are the brightest (intrinsically).
How are stars on the upper left end of the main sequence different from those on the lower right end?
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.

The hotter the star, the brighter. Ex: A stove

In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
IN main sequence stars what is the relationship between brightness and temperature?
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
What indicates stars of brightness and temperature?
The color of stars determines temperature. Red/brown stars are cooler, blue stars are hotter, and yellow stars are in between. Brightness also has some correlation with color. Both are based on many varying factors however.
What does the Hertzsprung-Russell diagram show about main-sequence stars?
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature

Is the sun hotter or cooler than most other main-sequence stars?
Beacuse penis.
Type of stars in the H-R diagram?
The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot. Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.
Are big stars cold?
No. All stars are hot. For stars on the main sequence, the largest it is, the hotter it is. When a star leaves the main sequence to become a giant or supergiant it will cool down, but will remain hot enough to glow brightly.
How are stars on the upper left end of the main sequence different from those on the lower right end?
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
