Types of Stars by Size, Color and Life Cycle

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.

The Brightness Of Stars

2. The Brightness Of Stars

This lesson will define and describe important terms related to a star's brightness, including luminosity, intrinsic brightness, apparent brightness, and more.

Relating a Star's Brightness to Luminosity

3. Relating a Star's Brightness to Luminosity

This lesson will explore how luminosity, apparent brightness, and distance are related to one another using the inverse square law. You'll also learn how luminosity can be gauged based on distance and apparent brightness.

Using the Magnitude Scale to Compare Star Brightness

4. Using the Magnitude Scale to Compare Star Brightness

This lesson will describe the magnitude scale, apparent brightness, and apparent visual magnitude. It will also teach you how to compare the brightness of stars.

Determining the Temperature of a Star

5. Determining the Temperature of a Star

This lesson will explain to you the concepts of a spectrum, electromagnetic radiation, the temperature of a faraway star and how that relates to something known as a blackbody curve and Wien's law.

How to Find the Size of a Star

6. How to Find the Size of a Star

This lesson will tell you how astronomers figure out the size of stars. You'll learn it has to do with a star's temperature, luminosity, and a cool thing known as the H-R diagram.
