6. Microlensing, Astrometry and Other Methods
Μεταφορτώθηκε στις 29 Σεπ 2008
Frontiers/Controversies in Astrophysics (ASTR 160)
The
class begins with a discussion on transits important astronomical
events that help astronomers to find new planets. The event occurs when a
celestial body moves across the face of the star it revolves around and
blocks some of its light. By calculating the amount of light that is
being obscured astronomers can obtain important information about both
star and planet, such as size, density, radial velocity and more. The
concept of planetary migration is explained in order to better
understand the dramatic differences between bodies in the Inner and
Outer Solar System. Finally, potential problems in the Solar System that
may occur as a result of migration are addressed.
00:00 - Chapter 1. Complexities and New Observations on Hot Jupiters
07:38 - Chapter 2. Discovery of Planetary Transits
19:53 - Chapter 3. Limits of Finding Planets Directly from Transits
28:54 - Chapter 4. Metallicity and Planetary Migration
43:32 - Chapter 5. Consequences and Limits of the Idea of Planetary Migration
