ASTR 103 Lecture Notes - Lecture 35: Formation And Evolution Of The Solar System, Escape Velocity, Plate Tectonics
Document Summary
List the general characteristics of the solar system (type of objects and regions) Understand the 3 criteria to be labeled a planet. Note how definition has evolved historically (number of planets) Understand the solar nebula theory (and how it gives us what we observe in the solar system today) Understand the condensation sequence and how it governed the formation of terrestrial and jovian planets. Extrasolar planets- our theory of solar system formation suggests that planets should be common. Early stages of planet formation (dusty disks) are easy to directly observe, fully formed planets are very difficult to observe- we need to look for the effects they have on their host stars. Radial velocity techniques- method by which most extrasolar planets have been identified. Be able to match up planet/star positions in the orbits with points on the radial velocity curve and identify when light is blue-shifted/red-shifted and radial velocity is negative/positive.
