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. They have fewer heavy elements, either by being older or being in regions where no heavy-element producing predecessors would be found.
What is a Population II star?
Population II stars Population II, or metal-poor, stars are those with relatively little of the elements heavier than helium. Intermediate Population II stars are common in the bulge near the centre of the Milky Way, whereas Population II stars found in the galactic halo are older and thus more metal-deficient.
How do population I stars differ from Population II stars quizlet?
Population I stars are usually the blue younger stars. They orbit in the disk and they are relatively rich in metals. Population II stars are the red, older stars that lies in the bulge and halo of the Galaxy. They orbits in the elliptical orbits in the halo.
What is the difference between population 1 and 2 stars?
Population I stars are relatively young stars which have formed within the last few billion years. Extreme Population I stars (the most metal rich stars) are found only in the spiral arms; these are the youngest stars. Population II stars are metal poor stars; they contain about 0.1 percent metals.
In which part of the Milky Way are Population II stars most likely to be found?
globular clusters
RR Lyrae variable stars and other Population II stars are found in the halos of spiral galaxies and in the globular clusters of the Milky Way system. Large numbers of these objects also occur in elliptical galaxies.
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.
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.
Where are the population 2 stars found?
RR Lyrae variable stars and other Population II stars are found in the halos of spiral galaxies and in the globular clusters of the Milky Way system. Large numbers of these objects also occur in elliptical galaxies.
How are Population II stars different than the sun a population I star group of answer choices?
How are population II stars different than the sun, a population I star? Population II stars are lower in heavy elements (metals) than population I stars. lobular clusters.
What is the difference in composition between Population I and Population II stars which populations probably formed first and how do you know?
(Population I is the name given to the stars found within… Population I consists of younger stars, clusters, and associations—i.e., those that formed about 1,000,000 to 100,000,000 years ago. Population II consists of the oldest stars and clusters, which formed about 1,000,000,000 to 15,000,000,000 years ago.
