What is the difference between population 1 and 2 stars?

What is the difference between population 1 and 2 stars?

Population I stars are metal rich stars; they contain about 2-3 percent metals. Intermediate Population I stars (like the Sun) are located through the disk. They are slightly less metal rich. Population II stars are metal poor stars; they contain about 0.1 percent metals.

What is the difference between population I and Population II stars describe each and identify their differences?

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.

What is the difference between a population I II and III star?

By definition, each population group shows the trend where decreasing metal content indicates increasing age of stars. Hence, the first stars in the universe (very low metal content) were deemed Population III, old stars (low metallicity) as Population II, and recent stars (high metallicity) as Population I.

What is the difference between population I and Population II stars in terms of chemical composition?

Population I stars are younger stars found in the disk of the galaxy that contain lots of atoms heavier than helium (metals). Population II stars are older, metal-poor stars found in a galaxy’s nuclear bulge, halo, and globular clusters.

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.

How are Population II stars different than the sun a population I star?

How are population II stars different than the sun, a population I star? Population II stars are lower in metals than population I stars. Which of the following are problems facing the traditional hypothesis of the formation of the Milky Way? Not all globular clusters have the same age.

What are Population II stars quizlet?

population II stars. stars poor in atoms heavier than helium ; relatively old stars nearly always found in the halo, globular clusters, or the central bulge. population I stars. stars with significant amounts of atoms heavier than helium; relatively young stars nearly always found in the galactic disk.

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?

What are population II stars quizlet?

What distinguishes the different stellar populations in our galaxy?

We now know that the populations differ not only in their locations in the Galaxy, but also in their chemical composition, age, and orbital motions around the center of the Galaxy.

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?

What is meant by the term population I stars?

Population I consists of younger stars, clusters, and associations—i.e., those that formed about 1,000,000 to 100,000,000 years ago. Certain stars, such as the very hot, blue-white O and B types (some of which are less than 1,000,000 years old), are designated as extreme Population I objects.

How are populations I and II stars classified?

Populations I and II Stars. Stars may be classified by their heavy element abundance, which correlates with their age and the type of galaxy in which they are found. Population I stars include the sun and tend to be luminous, hot and young, concentrated in the disks of spiral galaxies.

How are populations I and II different from each other?

Populations I and 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 systems.

Where are the population 1 stars located in the universe?

Population I stars include the sun and tend to be luminous, hot and young, concentrated in the disks of spiral galaxies. They are particularly found in the spiral arms.

Where are population II stars in the Milky Way?

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. This article was most recently revised and updated by Amy Tikkanen, Corrections Manager.
