Ch 18: The Birth and Life of Stars: Help and Review

About This Chapter

The birth and life of stars chapter of this Intro to Astronomy Help and Review course is the simplest way to master understanding the birth and life of stars. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of the birth and life of stars.

Who's it for?

Anyone who needs help learning or mastering Intro to Astronomy material will benefit from taking this course. There is no faster or easier way to learn introductory astronomy. Among those who would benefit are:

  • Students who have fallen behind in understanding the birth and life of stars
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about the birth and life of stars
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the birth and life of stars chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.

What is the Interstellar Medium?

1. What is the Interstellar Medium?

We'll explore something known as the interstellar medium, the birthplace of stars around our universe. You'll learn what it is made of, what interstellar dust is, and why it is there in the first place.

Young Stars & Stellar Associations

2. 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.

Emission, Dark, and Reflection Nebulae

3. Emission, Dark, and Reflection Nebulae

Did you ever hear about the famous Horsehead Nebula? Do you know why it looks dark like that and why the colors around it are such a pretty pink and blue? You'll definitely find out in this lesson as we explore emission, reflection, and dark nebulae!

How Does the Interstellar Medium Help Form Stars?

4. 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.

Young Stellar Objects and Protostellar Disks

5. Young Stellar Objects and Protostellar Disks

Birth lines, bipolar flows, protostellar disks, and young stellar objects. What do these have to do with star formation? How do they clue us into planetary formation? Check this lesson out for that and lots more info.

Nuclear Fusion & Star Formation

6. 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.

Star Formation: Main Sequence, Dwarf & Giant Stars

7. 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.

H-R Diagram: Definition & Purpose

8. H-R Diagram: Definition & Purpose

The Hertzsprung-Russell provides important information about stars such as color, temperature and luminosity. Check out which stars are blue, hot and red, and which ones are so cool they're in a class by themselves.

What is a Radiation Zone?

9. What is a Radiation Zone?

Did you know that inside of the Sun there are different layers where energy can travel? Explore this lesson to learn about one of those layers called the radiation zone. Discover what a radiation zone is and its role inside the Sun.

What is Apparent Brightness?

10. What is Apparent Brightness?

Looks can be deceiving. This old phrase is particularly true when talking about apparent brightness. In this lesson, we will define apparent brightness, discuss how scientists use it when studying stars, and point out a major drawback.

What is a Binary Star System?

11. What is a Binary Star System?

Our solar system, with its single sun, is actually quite rare. Most star systems contain solar twins, or binary stars. Read on to learn more about these interesting star systems and then check your understanding with a short quiz.
