In this question fully explain the following: • Why only 90% appear on the main sequence Why the other 10% are off the main sequence (red giants, super giants, and white dwarfs) How this can be explained with fusion, and stellar evolution, and equilibrium

In the hr diagram 90 percent of all stars are. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram ... 21.10.1999 · According to our best available estimates, stars having about 90 percent of the sun's mass are just now starting to die in the globulars. These stars are most probably around 15 billion years old ... Stars with an initial mass up to about 90 times the sun, or a little less at high metallicity, result in a type II-P supernova, which is the most commonly observed type. At moderate to high metallicity, stars near the upper end of that mass range will have lost most of their hydrogen when core collapse occurs and the result will be a type II-L supernova. At very low metallicity, stars of ... (Note that his arrow only applies to main sequence stars, but that is over 90% of stars.) (DONE) Figure 1: Conceptual HR Diagram. L T R M. The “brightest stars” are putting out a very large amount of energy. By putting out a large amount of energy the stars are able to shine brightly, more so than the more common stars.

In a hertzsprung Russell diagram where are 90 percent of all stars found. ... Circini is located near the upper left hand corner in the HR diagram. Circini is hotter and more luminous than the sun. ... All stars spend approximately the same amount of time on the main sequence. Like carbon stars, nearly all known class S stars are asymptotic-giant-branch stars. The spectral type is formed by the letter S and a number between zero and ten. This number corresponds to the temperature of the star and approximately follows the temperature scale used for class M giants. The most common types are S3 to S5. The non-standard designation S10 has only been used for the star Chi ... H–R diagram for the 100 brightest stars (open circles) and the 90 nearest ... After the core of a star in its red giant phase has burnt all its He into C ...
