WELCOME! to the home page for ASTR 5820: Origin and Evolution of Planetary Systems. The aim of this course is to explain how planets (including both terrestrial planets and giant planets) form from the protoplanetary disks that are observed around young stars, and to assess how the early evolution of planetary systems due to dynamical processes impacts what we observe today. Two of the `big picture' questions we'll be addressing are: (1) Can we understand the architecture of our own Solar System? and (2) Is our Solar System the typical outcome of the planet formation process? The course syllabus explains the most important class policies.

OUTLINE We'll broadly cover the process of planet formation and planetary system evolution in the same order in which we think it occurs in Nature:
 ·  Introduction to the salient features of the Solar System and extrasolar planetary systems
 ·  Structure and evolution of protoplanetary disks
 ·  Planet formation: starting from dust, then planetesimals, terrestrial and giant planets
 ·  Planetary system evolution: migration and dynamical stability

PROBLEM SETS

Problem Set #1

LECTURE NOTES The lecture notes from the version of this class taught in 2008 are available online. There will be some different material covered this time around, reflecting both developments over the last two years and changes in my thinking as to what are the most important topics. But overall these notes will give a close approximation of the content of the course.

TEXTBOOKS My own textbook, Astrophysics of Planet Formation, provides a more in-depth treatment of the class material than there is space for in the lecture notes. Other books that I recommend are Planetary Sciences (de Pater and Lissauer), which provides a broad introduction to much of planetary science, and Solar System Dynamics (Murray and Dermott), which is the standard reference for serious students of planetary dynamics.

CODES The Mercury N-body code (tar file)
HNBody
Hermite code, from Piet Hut - not suitable for very long integrations but easy to modify and adequate for relatively short runs

VINTAGE TEXTBOOK The theoretical study of planet formation owes a tremendous debt to Victor Safronov, whose work on the Evolution of the protoplanetary cloud and formation of the earth and the planets was far ahead of its time. This book (in English translation!) is sporadically available second hand through Amazon - I have a copy if anyone's interested. I gather NASA will still sell you a new copy if you ask too.
