Frontiers and Controversies in Astrophysics 

 

 

Lecture 5 - Planetary Transits 

 

 

 

Overview:

Professor Bailyn talks about student responses for a paper assignment on the controversy over Pluto. The central question is whether the popular debate is indeed a "scientific controversy." A number of scientific "fables" are discussed and a moral is associated with each: the demotion of Pluto (moral: science can be affected by culture); the discovery of 51 Peg b (morals: expect the unexpected, and look at your data); the disproof of pulsation as explanation for the Velocity Curves (moral: sometimes science works like science).

Frontiers and Controversies in Astrophysics 

 

 

Lecture 4 - Discovering Exoplanets: Hot Jupiters 







Overview:

 

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 planet's 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.
