About This Chapter
Star Types & Significance - Chapter Summary
This chapter's lessons look at how stars are formed and the stages they go through before their demise. Our instructors will present information about types of stars and how they can be classified by size and color. You'll learn about main sequence stars and how they get their energy.
Other lessons look at the characteristics of star clusters in the Milky Way and at binary stars. By the time you've finished studying all the lessons in this chapter, you should know more about:
- The life cycle of stars
- Types of stars
- Characteristics of a main sequence star
- The two kinds of star clusters
- Classifications of binary stars
You can watch these short lessons, most averaging about five minutes, from a computer or mobile device as your schedule permits. The quizzes that follow the lessons provide the opportunity to check your learning. If you need to review major points from the videos, video tags make it easy to go to the right spot in the lesson.
1. Formation, Types & Life Cycles of Stars
After reading this lesson, you will be able to describe how stars form and what form they take as well as describing the common cycles of their lives. A short quiz will follow.
2. 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.
3. 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.
4. 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.
