How many stars are main sequence stars?
Of the stars you can see from Earth, 90% are in the main sequence.
90 percent of the stars in space are what kind of stars?
It has been estimated that as many as 85% of all stars in our galaxy are "white dwarf" stars. Up to 97% of all stars will likely end up as white dwarfs.Correction: About 90% of the stars in space are actually Main Sequence stars.
How many stars are in eridanus?
24 (main stars).
What are some examples of main sequence stars?
The most massive star (The star with the most mass) is a star in a super star cluster called R136 or RMC 136 in the Large Magellanic Cloud (LMC). [See related link for more information] The star, for all its fame has a rather unremarkable name of R136a1. It has the mass of about 265 -> 300 solar masses (256 x the mass of the Sun - See related question). See related link [BBC] for a pictorial size comparison. It is a blue supergiant with a spectral type of O3. Because of its mass and intense luminosity (10 million times that of our own Sun) it, astronomically, will have a very short lifetime in the millions of years rather than billions. At the end of its life, R136a1 will explode as a supernova and because of its relatively close distance to Earth (165,000 light years/ALU [See related question] it might be visible during the day. This question is about the most massive star (mass), not the largest (Radius) [See related question]
How many stars are in the constellation Delphinus?
There are five main stars.
How many stars are main sequence stars?
Of the stars you can see from Earth, 90% are in the main sequence.
What is the general size of a main sequence?
It can have many different sizes. Only the largest giants are no longer main sequence stars.
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.
How many stars are in our solar system and what type?
There is one star in our solar system: the sun. It is a yellow main sequence star.

How many pages does Off the Main Sequence have?
Off the Main Sequence has 738 pages.
What is sequence stars?
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.

How many years do spectral class O5 stars remain on the main sequence?
It all depends on the mass of the star 1exp10*(m/l) where "m" is mass and "l" is luminosity. Will give you an approximate period of the stars life.
How many stars are in eridanus?
24 (main stars).
How many stars are in Leo?
9 main stars
