Study Plan

Learning Goals

By the conclusion of this chapter, you should be able to:
  1. Summarize the role that gravity, energy, and angular momentum play in the formation of stars and planets.
  2. Describe the modern theory of planetary system formation.
  3. Explain how temperature in the disk that surrounds a forming star affects the composition and location of planets, moons, and other bodies.
  4. Compare and contrast the processes that resulted in the inner and outer planets that form the Solar System.
  5. Describe how astronomers find planets around other stars and what those discoveries tell us about our own and other solar systems.

Prepare and Assess


    1. Solar System Formation
      Section: 7.1
    2. Traffic Circle
      Section 7.2
    1. Planet Formation Temperatures Plot
      Shows planet formation temperature as a function of distance from the Sun. Also indicates the state (gas or solid) of several substances at the given distance and temperature.
    2. Radial Velocity Graph
      Shows a star and a planet in orbit around each other while tracing out the star's radial velocity curve.
    3. Exoplanet Transit Simulator
      Demonstrates how a planet passing in front of its parent star can cause dips in the star's light curve, potentially leading to the planet's detection.
    4. Extrasolar Planet Radial Velocity Demonstrator
      Demonstrates how the spectrum of a star is shifted as it and its planet orbit their common center of mass.
    5. Radial Velocity Simulator
      Models the motion of an extrasolar planet and its star around their common center of mass, and the effect this motion has on the star's observed radial velocity.
    6. Doppler Shift Demonstrator
      Shows circular waves expanding from a source. Movement of the source or observer affects the frequency of the waves seen by the observer, demonstrating Doppler shift.
    7. Center of Mass Simulator
      Shows how the center of mass of two objects changes as their masses change.
    8. Circumstellar Habitable Zone Simulator
      Demonstrates location and evolution of the stellar habitable zone, which is the region around a star where surface water may exist on an Earth-like planet.
