        Lecture Details

        FrontiersControversies in Astrophysics (ASTR 160) The formation of planets is discussed with a special emphasis on the bodies in the Solar System. Planetary differences between the celestial bodies in the Inner and Outer Solar System are observed. Professor Bailyn explains how the outlook of our Solar System can predict what other star systems may look like. It is demonstrated how momentum equations are applied in astronomers search for exoplanets. Planet velocities are discussed and compared in relation to a planets mass. Finally, the Doppler shift is introduced and students learn how it is used to measure the velocity of distant objects, such as galaxies and planets. 0000 - Chapter 1. Theory of Planetary Formation 1204 - Chapter 2. Observing Moving Exoplanets and Stars 2345 - Chapter 3.
