Star Types and Significance - Chapter Summary and Learning Objectives

Astronomy is a very broad field, and stars are just one kind of entity found in the night sky, although their presence and role in astronomic activity can be significant. In this chapter, you'll access video lessons to learn about the different kinds of stars and the common properties they share throughout their life cycles. Explore why the stars discussed here are important to an understanding of astronomy. Video lessons also include a discussion of stars' motion and mass, as well as the Doppler shift. You'll learn about key concepts related to the Doppler shift, like blueshift, redshift, relative mass, and stellar combinations. By the end of the chapter, you should be able to:

  • Identify common features of stars according to their type
  • Define 'main sequence star'
  • Describe star clusters
  • Define 'binary star'
  • Understand the concept of the Doppler shift
  • Name several types of stellar combinations
