Which main sequence stars are most massive?
Main sequence stars that are most massive are O-type stars, which can be more than 16 times the mass of the Sun. These stars are among the hottest and brightest in the main sequence and have relatively short lifespans compared to lower mass stars.
Are the hottest main sequence starts also the most massive?
Yes, generally the hottest main sequence stars are also the most massive. This is because more massive stars have higher core temperatures and pressures, resulting in hotter surface temperatures. Therefore, there is a direct correlation between a star's mass and its surface temperature on the main sequence.
Is the color at the star related to its size?
Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
How does star color relate to mass?
There is no simple relation. The color does not depend only on the mass. The same star can change color, without a significant change in mass. For example, our Sun is currently yellow; in a few billion years, it is expected to get much larger, becoming a red giant. However, if we limit the sample of stars to those on the "main sequence" of the "HR diagram", there is something of a relation between mass and color. The most massive stars are blue or white. They are also hottest and most luminous. The least massive are the red dwarf stars, which are relatively cool and dim. Our Sun, which is a "main sequence" star at present, is somewhere in between those extremes. (There is a strong relationship between mass and luminosity for main sequence stars. The HR diagram, of course, shows there is a relationship between luminosity and color for the main sequence stars.)
Are main sequence stars all alike in their luminosity and temperature?
No. Main sequence stars vary greatly in both temperature and luminosity. The least massive stars, red dwarfs, can have temperatures as low as 2,300 Kelvin and luminosity as low as 0.015% that of the sun. The most massive stars, which are blue in color can have temperatures as high as 50,000 Kelvin and may be hundreds of thousands times more luminous than the sun.
What Color is the most massive main sequence star?
its a blue color
Which main sequence stars are most massive?
Main sequence stars that are most massive are O-type stars, which can be more than 16 times the mass of the Sun. These stars are among the hottest and brightest in the main sequence and have relatively short lifespans compared to lower mass stars.
What color is the most massive type of mainsequence star?
The most massive type of main sequence star on the HR diagram would be indicated by the main sequence area at the top left of the HR diagram, which would be blue or violet in color. Zeta Puppis is an example of such a star. It comes in at 40 solar masses. It is classified as a type "O" star.
Is our sun the most or least massive of main sequence stars?
Neither, the sun is on the small side of the middle range of main sequence stars.
Are the hottest main sequence starts also the most massive?
Yes, generally the hottest main sequence stars are also the most massive. This is because more massive stars have higher core temperatures and pressures, resulting in hotter surface temperatures. Therefore, there is a direct correlation between a star's mass and its surface temperature on the main sequence.
What is the main sequence star's temperature most closely related to?
A main sequence star's temperature is most closely related to its color and brightness.
Is the color at the star related to its size?

As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
What color is a very hot main sequence star most likely to have?
blue

At the moment R136a1 still holds the title, so see related question.

Which main-sequence stars are brightest?
Main-sequence stars that are the brightest are typically O-type stars, which are the hottest and most massive. These stars emit intense ultraviolet radiation and have luminosities many times greater than that of the Sun. O-type stars are relatively rare, but they are some of the most brilliant and energetic objects in the universe.
