Ast 8011 Seminar Topics & Readings:

 

---General Notes---

 

1)   For each topic selected I have included some background readings that should be relatively easy to understand and will help with context and terminology. Please read these before the technical articles listed for discussion.

2)   While I have tried to keep the discussion literature as brief as possible, it will not be possible to discuss it in full detail. Your task centers on ferreting out the essential insights of the set and the critical information behind those.  That is an essential skill for a working scientist.

3)   The number of assigned papers varies from 1 to 3. I included what I thought was necessary to read in order to understand the issues. It is not necessary, however, that all the papers be reviewed individually in the class. Discussion leaders should establish discussion priorities that will maximize understanding of the full group of papers.

4) It is VERY important that you read the assigned preliminary readings BEFORE you read the journal literature assigned. All the topics have a large amount of terminology and phenomenology that we just do not have time to work through systematically in class.
