What type of star cluster is composed of population 2 stars?
Globular clusters
Globular clusters are composed of Population II objects (i.e., old stars).
Where can I find population 2 stars?
Population II stars are mainly found in the bulge and halo of galaxies.
Where are Population II stars found quizlet?
Population II stars tend to be found in globular clusters and the nucleus of a galaxy. They tend to be older, less luminous and cooler than Population I stars.
What is the difference between population I and Population II stars in what sense can the stars of one population be regarded as the children of the other population?
In what sense can the stars of one population be regarded as the children of the other population? Population I stars are those are metal rich. Population II stars are those that are metal poor. Metal-rich stars, like the Sun, are classified as Population I stars.
Which type of galaxy contains the most population II stars?
elliptical galaxies
In fact, elliptical galaxies contain primarily old, red stars (also known as Population II stars). Elliptical galaxies vary widely in size. Both the largest and the smallest known galaxies are elliptical. Very large elliptical galaxies can reach 300 million light years in diameter.
How are population 2 stars different from the Sun?
Population II stars in the outer galactic halo and in globular clusters have much lower abundances of the heavy elements—often less than one-hundredth the concentrations found in the Sun and in rare cases even lower. The oldest population II star discovered to date has less than one ten-millionth as much iron as the Sun, for example.
Where are population II stars found in the Galaxy?
Population II stars are metal poor stars; they contain about 0.1 percent metals. They are found in the spherical component of the Galaxy (the halo and the bulge). They have randomly tipped, elliptical orbits which can plunge through the disk of the Galaxy and which take some of them (the halo stars) to large distances from the center.
What are populations I and II in astronomy?
In Populations I and II II, in astronomy, two broad classes of stars and stellar assemblages defined in the early 1950s by the German-born astronomer Walter Baade. The members of these stellar populations differ from each other in various ways, most notably in age, chemical composition, and location within galactic….
Where are the extreme population 2 stars located?
Extreme Population II stars (the most metal poor) are found in the halo and the globular clusters; these are the oldest stars. Intermediate Population II stars are located in the bulge. They are slightly more metal rich than the extreme Population II stars, but less metal rich than the intermediate Population I stars.
