Students will review:
This chapter helps students review the concepts in a star types and significance unit of a standard intro to astronomy course. Topics covered include:
- Types of stars by size, color and life cycle
- Main sequence stars defined
- Types of star clusters
- Binary stars defined
1. 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.
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.
5. Antares: Star & Facts
In this lesson, you will learn about a large, red object in the night sky visible from Earth. No, it's not the planet Mars; it is the star named Antares. Learn about where Antares is located and some of the properties that make Antares so special.
6. Brown Dwarf Star: Definition & Overview
If you failed to become a star, could you still be cool? Brown dwarf stars are. Read about how these unusual sub-stellar objects were discovered and what we know about them today. You can also take a quiz to test your understanding.
7. Protostar: Definition, Formation & Facts
This lesson will examine the protostar, including its physical features and the process by which it forms. We will also discuss the way in which a protostar develops into a regular star. A short quiz will follow.
8. What is a Neutron Star? - Mass, Density & Weight
Neutron stars are dense objects found throughout the universe. Composed of neutrons, they have more mass than the sun but are only a few kilometers wide. This lesson will cover the properties of neutron stars.
