        Lecture Details

        FrontiersControversies in Astrophysics (ASTR 160) 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). 0000 - Chapter 1. A Case for Pluto? Interactions between Culture and Science 0853 - Chapter 2. Velocity and Center of Mass 2423 - Chapter 3. Observations of Hot Jupiters and the Selection Effect 3155 - Chapter 4. Hot Jupiters - Double or Pulsating Stars? 3949 - Chapter 5. Measuring Doppler Shifts to Understand Hot Jupiters Complete course materials are available at the Open Yale Courses website httpopen.yale.educourses This course was recorded in Spring 2007.
