30% of your grade in this course will come from a combination of a report and an associated 10 minute presentation on a Paper that involves some application of Atomic, Molecular, or Radiation Physics in Astronomical or Planetary Sciences.

You may reserve a paper to report on, and I will post reservations of papers and topics on this webpage. If you have a preference, then obviously it is in your interest to reserve a paper as early as possible.

Your writing should be clear, concise, and correct. Part of the grade on your report will be based on the quality of the writing.

Your report here should be in two parts: a description, and a critique. The first part, the description, should describe succinctly the principal arguments and results of the paper. The second part, the critique, should be in the style of a ``referee's report'', and should bring out the merits and faults of the paper.

You should imagine that the author(s) will read the report. Therefore you should be polite but factual at all times. If you make general criticisms, you should back these up with detailed specifics.

As referee, it is your responsibility to go through the paper with a fine toothcomb to check for errors, unclear statements, and misprints. If you like, you can mark up a copy of the paper, but this should not take the place of your report.

I would imagine that your report might fill 3 typed pages, but there is no hard and fast rule.


You should prepare your presentation on overhead transparencies. I would imagine that 3 transparencies would be entirely adequate, but there is no hard and fast rule.

If you want make a collaborative presentation with someone else, that is fine. However, you should write separate reports. You may not make presentations on exactly the same topic as someone else.

Suggested Topics

  1. Ozone
  2. Greenhouse effect
  3. Aurora
  4. 21cm hyperfine line of hydrogen
  5. Herbig-Haro objects
  6. The glowing rings around SN 1987A
  7. Water masers in M106 (NGC4258)
  8. Photoionization of the Intergalactic Medium
  9. X-ray emission from clusters of galaxies
  10. A paper of your choice, perhaps in your own special field of interest
