PHYS3037: Plasma and Astrophysics

Looking at the sky it is easy to forget our Sun and the stars are continuous giant nuclear explosions, or that nebulas are vast fields of ionized gases, all obeying the same laws of physics as anything else in the universe. Astrophysics gives us great insight in the larger structures of the universe, and plasma physics is key to understanding matter in space, but also in fusion reactors or for advanced material processing. This selective unit in the physics major will provide an introduction to astrophysics and plasma physics, complemented with experimental labs. You will study three key concepts in astrophysics: the physics of radiation processes, stellar evolution, and binary stars. You will gain understanding of the physics of fundamental phenomena in plasmas and apply basic methods of theoretical and experimental plasma physics. Examples will be given, where appropriate, of the application of these concepts to naturally occurring and man-made plasmas. You will learn and apply new experimental and data analysis techniques by carrying out in-depth experimental investigations on selected topics in physics, with expert tutoring. In completing this unit you will gain understanding of the foundations of modern physics and develop skills in experimental physics, measurement, and data analysis.

  • Assignments: There are three coursework assignments in this unit, one per module and one larger problem assignment using aspects
    of both modules. You are encouraged to start early on the problem assignment, as you will be able to solve aspects from it as early as it is released.
  • Plasma physics online quizzes: There will be compulsory online lectures and a small quiz before each lecture starting from week 7; material covered in lectures will assume the reading has been done and will be part lecture, part tutorial. Each lecture's pre-reading and/or quizzes will need to be completed by the beginning of the lecture.
  • Astrophysics computer labs: You only need to attend one lab session, though if you have work to make up, you're welcome to attend the other sessions as well. Each lab consists of three checkpoints; all checkpoints must be handed in and marked off by the following lab session.
  • Experimental physics lab books: Every student will carry out two experiments, lasting 3x4hour sessions each, or one double experiment lasting 6x4h sessions. Experiments are to be completed in the times allocated to you; this is part of the assessment. Your lab work will be marked on what you achieve in this time only. You must record the experiments you perform in a University-supplied logbook as each experiment is carried out. This is the written record of the experiment/s.
  • Experimental physics report and peer review: You will be required to write up one report on one of the experiments you do, based on the material already in your logbook. Reports are to be written in the style of a scientific paper in a specific journal.
  • Final exam: The final exam will have questions covering all coursework aspects of this course (astrophysics and plasma physics), and will be entirely paper- based. This is a closed book exam.

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

For more information see sydney.edu.au/students/guide-to-grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University’s graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. demonstrate an understanding of key concepts in two areas of physics - astrophysics and plasma physics
  • LO2. apply these concepts to develop models, and to solve qualitative and quantitative problems in scientific contexts, using appropriate mathematical and computing techniques as necessary
  • LO3. carry out and analyse experiments to measure specific effects
  • LO4. compare and critique experimental approaches
  • LO5. communicate scientific information appropriately, through written work
  • LO6. analyse a physical problem in plasma physics and astrophysics, and develop a formalism appropriate for solving it
  • LO7. demonstrate a sense of responsibility, ethical behaviour, and independence as a learner and as a scientist.
