Do the stars on the main sequence illustrate the mass-luminosity relationship?

Luminosity depends directly on mass because more massive main-sequence stars do not need to graviationally contract as far to reach fusion temperatures, and so they have a larger volume and contain a much larger amount of light energy, which diffuses out and generates a higher luminosity, very roughly in proportion to the higher volume.

Are most stars main sequence stars?
yes
What characteristics make white dwarf stars different from main sequence stars?
Beacuse they are dimmer, but they're also bigger than the main sequence stars.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
Which part of the main sequence in the HR diagram contains the stars that took the longest to reach the main sequence?
The HR diagram does not reference stars on their way to the main sequence, only during or after.
What is the composition of main sequence stars?
Such stars consist mainly of hydrogen-1.
Are main sequence stars called medium sized stars?
No. Main sequence stars are simply stars that are fusing hydrogen into helium and have a specific relationship between color and luminosity. They range from red dwarfs to large O-type main sequence stars.
What is the relationship between luminosity and temperature for main sequence stars?
On such a diagram, those stars lie on a curve called the "main sequence". It is not a simple relationship - for example, it isn't a straight line on the diagram. Therefore, it isn't easy to describe in words. It's best if you look up "Main sequence", for example on the Wikipedia, and look at the corresponding diagram.
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.
How many stars are main sequence stars?
Of the stars you can see from Earth, 90% are in 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.
About 90 of all stars are what kinds of stars?
main sequence stars , our sun is also a main sequence star
What percentage of stars are main sequence stars?

Are stars on the main sequence hot?
Main sequence stars include the hottest stars as well as the coolest ones.
Stars are now classified by how?
The Hertzsprung-Russell ishowing the relationship between the stars' absolute magnitudes or luminosities. The sequence is Obafgkmrns. Each letter representing a classification of type.
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.
