13. Stellar Mass Black Holes (cont.)
Μεταφορτώθηκε στις 29 Σεπ 2008
Frontiers/Controversies in Astrophysics (ASTR 160)
Class
begins with clarification of equations from the previous lecture. Four
post-Newtonian gravitational effects are introduced and discussed in
detail. The first of these is the so-called Perihelion Precession, which
occurs when the major axis of a planet's elliptical orbit precesses
within its orbital plane, in response to changing gravitational forces
exerted by other planets. Secondly, deflection of light is described as
the curving of light as it passes near a large mass. Gravitational
redshift is explained as a frequency effect that occurs as light moves
away from a massive body such as a star or black hole. Finally, the
existence and effects of gravitational waves are discussed. The lecture
closes with a brief history of the 1919 eclipse expedition that made
Einstein famous.
