Information on millions of stars shows that there is a relationship between temperature and brightness. Surface temperature is measured in degrees C and brightness is measured in absolute magnitude (the star's brightness at a standard distance).
If all the stars are plotted on a graph of temperature against absolute magnitude, called a Hertzsprung-Russell diagram, very many of them lie close to a straight line that is called the Main Sequence. There are some stars that do not lie on the Main Sequence, notably the red giants that are very bright despite having a relatively low temperature.
The Sun is right in the middle of the Main Sequence showing it is an average star in the middle of its life and very stable.
What else can I help you with?
Is most stars sequence stars?
"main sequence" is the tern.
What are the two stars that are not in the main sequence?
There are billions of stars that are not on the main sequence.
What are the stars in the main sequence?
The smallest stars in the main sequence are the stars with cooler surface temperatures.
What kind of stars are 90 of all Stars?
main sequence stars , our sun is also a main sequence star
About 90 of all stars are what kinds of stars?
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
What type of stars are most stars?
main sequence stars
What is a diagonal band of stars on the H-R diagram?
Main sequence stars.
Are there main sequence stars in the Milky Way?
Main sequence stars are found in all galaxies.
What percentage of stars are main sequence stars?
Approximately 90% of stars in the universe are categorized as main sequence stars. These stars, like our Sun, are in the stable phase of their lifecycle where they fuse hydrogen into helium in their cores. Main sequence stars vary in size and temperature, leading to differences in brightness and color.
Do red main sequence stars have the highest surface temperature?
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
Are most stars main sequence stars?
yes
What are the main sequece of stars?
