The Butterfly Star Cluster M6 By Celestial Image Co Star Cluster Space And Astronomy Andromeda Galaxy

Most stars in the cluster are yellow or reddish in color.

. C Open and globular clusters each typically contain a. All stars in the cluster are approximately the same age. E Globular cluster stars are very metal-poor relative to the Sun.

Two stars both lie on the main sequence Star X. Since Pleiades contain B type stars the cluster cannot be much older than 100 million years. The age of stars in a cluster can be determined by.

Open clusters are found both in the disk and the halo of the galaxy while globular clusters are found only in the halo. Clusters are too far to. All stars in the cluster have approximately the same mass.

Most stars in the cluster are yellow or reddish in color. A All stars in the cluster are approximately the same color. Both in the disk and the halo of the galaxy.

A Open clusters are found only in the disk of the galaxy while globular clusters may be found both in the disk and the halo of the galaxy. In order to understand star clusters we need to be able to estimate. B There are usually about a few hundred stars loosely held together by gravity.

Which of the following statements comparing open and globular star clusters is true. C All stars in the cluster have approximately the same mass. Open clusters have been found only in spiral and irregular galaxies in which active star formation is occurring.

B Stars in open clusters are relatively young while stars in globular clusters are very old. The brightest of the Pleiades are visible to the naked eye. Over time radiation pressure from the cluster will disperse the molecular cloud.

The Pleiades Seven Sisters is an example of an open cluster. A All stars in the cluster formed at about the same time. All stars in the cluster are approximately the same age.

There is an approximately equal number of all types of stars in the cluster. C Globular cluster ages increase with distance from the Milky Way. Determining the main sequence turnoff point.

D There is an approximately equal number of all types of stars in the cluster. Which one of the following is a true statement for a globular cluster and a false statement for an open cluster. Associations contain mainly older stars.

Which of the following statements about globular clusters is true. The brightest of the Pleiades are visible to the naked eye. C All stars in the cluster had approximately the same initial chemical composition.

B There are usually about a few hundred stars loosely held together by gravity. Pleiades are an open cluster. D Globular clusters are distributed spherically around the Milky Way.

Which of the following statements about a globular cluster is true. Which of the following statements about an open cluster is true. Associations of stars extend over larger distances than open clusters.

Young open clusters may be contained within the molecular cloud from which they formed illuminating it to create an H II region. All stars in the cluster are approximately the same age. C All stars in the cluster had approximately the same initial chemical composition.

Therefore Star X is larger in radius than Star Y. B Stars in open clusters are relatively young while stars in globular clusters are very old. Star X is spectral type F.

A Globular clusters contain many thousands of stars. A Open clusters are found only in the disk of the galaxy while globular clusters may be found. Cluster ages can be determined from.

Which of the following statements are true. Two stars have the same luminosity. Subaru means Pleiades in Japanese and the Subaru cars carry logos that depict the Pleiades.

Globular clusters typically contain a few hundred stars while open clusters typically contain tens to hundreds of thousands of stars. Typically about 10 of the mass of a gas cloud will coalesce. -Open clusters are found only in the disk of the galaxy while globular clusters may be found both in the disk and the halo of the galaxy-For both open and globular clusters we can assume that all the stars in a particular cluster are about the same age-Stars in open clusters are relatively young whereas stars in globular clusters are old.

Which of the following statements about open clusters is true. Clusters are too far to. Which of the following statements are true.

Mark all that apply-Pleiades are an open cluster-The brightest of the Pleiades are visible to the naked eye-Hyades are a globular cluster-The brightest of the Hyades are visible to the naked eye-Nonsense. The brightest of the Hyades are visible to the naked eye. The brightest of the Hyades are visible to the naked eye.

Which one of the following is a true statement for a globular cluster and a false statement for an open cluster. B All stars in the cluster are approximately the same age. Globular clusters contain more stars than open clusters and associations.

Which of the following statements about an open star cluster is true. B Globular cluster stars are more than 12 billion years old. Mark all that apply Pleiades are an open cluster.

Therefore star X is larger in radius than Star Y. Hyades are a globular cluster. While Star Y is spectral type K.
