Ch 13: CEOE Earth Science: Stars

About This Chapter

Prepare for the CEOE Earth Science exam by reviewing the key stars content in this chapter of the study guide. The different topics are presented in engaging video lessons.

CEOE Earth Science: Stars - Chapter Summary

The lessons in this chapter will review different types of stars along with their life cycles for your CEOE Earth Science test preparation. By the end of the chapter, you should be able to confidently answer any exam questions about the following:

  • The different classes of stars
  • How population I and population II stars differ
  • Kinds of star clusters
  • What pulsars are
  • Main sequence and binary stars

Short, engaging video lessons are accompanied by transcripts with important terms in bold print. You can easily rewatch key moments of the videos by using the Timeline, and test your understanding and retention of the material with self-assessment quizzes. Knowledgeable instructors are available to answer any questions you may have.

CEOE Earth Science: Stars Chapter Objectives

The CEOE Earth Science exam helps determine if you have the level of knowledge needed to teach earth science classes in Oklahoma. This computer-based exam covers foundations of scientific inquiry, space systems, atmospheric systems, geological systems, and water systems. The material covered by the Stars chapter is found in the space systems section of the exam, which constitutes about 20% of the entire test. All the questions in the space systems section are multiple choice.

How Telescopes Detect & Measure Light

1. How Telescopes Detect & Measure Light

This lesson will go over the numerous methods astronomers can use to detect and measure light, including photography, spectroscopy, photometry, and CCDs.

Types of Stars by Size, Color and Life Cycle

2. Types of Stars by Size, Color and Life Cycle

Learn to identify the different sizes and colors of stars and how they relate to the star life cycle. In this lesson, we'll talk about spectral classification, how many stars there are of each type and the approximate color of the different classes of stars.

Population I and Population II Stars

3. Population I and Population II Stars

This lesson will explore the different populations of stars in our galaxy, including population I and II stars, as well as where you can find them and what metals are to an astronomer.

What Are Pulsars?

4. What Are Pulsars?

This lesson will define and describe pulsars. Importantly, you'll learn why the term is a bit of a misnomer, what acts as a pulsar and why, and what it pulses out.

Types of Star Clusters

5. Types of Star Clusters

Our lesson will explore what star clusters are, the two types of star clusters, and their characteristics and differences as well as how we can figure out their ages using the H-R diagram.

What is a Main Sequence Star?

6. What is a Main Sequence Star?

This lesson will explain what a main sequence star is and how it evolves. You'll also learn about how the sun ages as a main sequence star and how that will affect life on Earth.

What Are Binary Stars?

7. What Are Binary Stars?

This lesson defines binary stars and describes the different kinds, including visual binary, astrometric binary, spectroscopic binary, and eclipsing binary stars. We'll also describe how orbits and mass relate to one another in a binary star system.

Young Stars & Stellar Associations

8. Young Stars & Stellar Associations

This lesson will describe the concept of a stellar association for you and how it differs from a star cluster. You'll also learn about the three general kinds of stellar associations: R associations, T associations, and OB associations.

How Does the Interstellar Medium Help Form Stars?

9. How Does the Interstellar Medium Help Form Stars?

This lesson will describe how the interstellar medium plays a role in the earliest phases of the formation of stars. We'll define what a protostar is, how gravity is important, and what a cocoon is in an astronomical sense.

Star Formation: Main Sequence, Dwarf & Giant Stars

10. Star Formation: Main Sequence, Dwarf & Giant Stars

Learn how stars are born, beginning with a protostar. Then learn about stars in later stages of life, including main sequence stars, brown dwarfs, red giants, and black holes.

Nuclear Fusion & Star Formation

11. Nuclear Fusion & Star Formation

This lesson will explain how the processes of stellar formation leads to nuclear fusion. We'll also define nuclear fusion and hydrostatic equilibrium, and find out why temperature is so important to all of this.

Life Cycle of Black Holes

12. Life Cycle of Black Holes

Learn about black holes, their myths and their reality. Learn how black holes form after stars undergo supernovae and create singularities. Discover how big black holes grow, how scientists find black holes and where black holes are located in the universe.

Life Cycle of Neutron Stars

13. Life Cycle of Neutron Stars

Discover the life of a neutron star, including how it's born after a supernova explosion and how its extreme pressure causes protons and electrons to combine into neutrons. Discover also how pulsars are rotating neutron stars that will eventually slow down to become regular neutron stars.

Supernova and Supergiant Star Life Cycle

14. Supernova and Supergiant Star Life Cycle

Learn about one of the biggest explosions known to humankind - a supernova. Follow a star's life cycle and learn how a star changes from a red giant to a supernova to a black hole or neutron star.

How Lower-Main-Sequence Stars Die

15. How Lower-Main-Sequence Stars Die

Not every star lives or dies the same way. Red dwarfs and medium-sized stars have key differences that determine their lifespan and how they die. This lesson will tell you why that is the case.
