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.

We can do something similar for stars. We find that, on average, 90% of all stars are located on the main sequence of the H–R diagram. If we can identify some activity or life stage with the main sequence, then it follows that stars must spend 90% of their lives in that activity or life stage. Understanding the Main Sequence Main sequence definition, a narrow band in the Hertzsprung-Russell diagram in which 90 percent of all observed stars are plotted. See more. H-R Diagram for Stars. A Most Important Diagram Classifying stars according to their spectrum is a very powerful way to begin to understand how they work. As we said last time, the spectral sequence O, B, A, F, G, K, M is a temperature sequence, with the hottest stars being of type O (surface temperatures 30,000-40,000 K), and the coolest stars ... We observed that 90% of all stars seem to follow the relationship; these are the 90% of all stars that lie on the main sequence in our H-R diagram. Our models and our observations agree. What about the other stars on the H-R diagram—the giants and supergiants, and the white dwarfs?

Around 90 percent of the stars in the Universe are main-sequence stars, ... Therefore blue giant simply refers to stars in a particular region of the HR diagram rather than a specific type of star. An example of a blue/white giant star is Alcyone in the constellation Taurus. -a diagonal area on an H-R diagram that includes -more than 90 percent of all stars. shooting star. another name for a meteor. red giant. A large, bright, cool star, late in it's life cycle ... Hertzsprung-Russell diagram, a graph that shows the relationship between magnitudes and temperature. ...
