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.
Which two groups of stars can have similar brightness?
Variable stars and main sequence stars can have similar brightness. Variable stars, like Cepheid variables, can fluctuate in brightness over time, while main sequence stars maintain a relatively stable brightness due to their fusion processes.
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
Where a main sequence star is located on the H-R diagram depends on its temperature and its?
The location of a main sequence star on the H-R diagram depends on its temperature and its luminosity (or brightness). Main sequence stars follow a diagonal band on the diagram, with hotter and more luminous stars located towards the top left and cooler and less luminous stars towards the bottom right.

In main-sequence stars how does brightness relate to temperature?
The brightness is very similar to the temperature, the brightness relies on the temperature
Temperature and brightness of stars are indicated by what?
Temperature of stars is indicated by their color, with blue stars being hotter than red stars. Brightness of stars is indicated by their luminosity, which is how much light a star emits.
Do stars get hotter as they age?
Yes, stars generally get hotter as they age due to the process of nuclear fusion in their cores, which increases the temperature and brightness of the star over time.
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 are the temperature and brightness of stars indicated by?
The temperature of a star is indicated by its color, with blue stars being hotter than red stars. The brightness of a star is indicated by its apparent magnitude, with lower numbers representing brighter stars.
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
What does a star's position in the main sequence tell you about the star?
A star's position on the main sequence indicates its mass, temperature, luminosity, and evolutionary stage. Stars fuse hydrogen into helium in their cores while on the main sequence. The more massive the star, the hotter, brighter, and shorter its lifespan.
