PHYS4037: Plasma and Astrophysics (Hons)

Semester 2, 2023 [Normal day] - Camperdown/Darlington, Sydney

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 unit will provide an advanced introduction to astrophysics and plasma physics, complemented by an extensive literature research project critically investigating a current research topic in plasma physics or astrophysics. 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. Examples will be given, where appropriate, of the application of these concepts to naturally occurring and man-made plasmas. In addition, you will carry out an in-depth critical analysis of a topic or your choice in astrophysics and/or plasma physics through a literature review research project. In completing this unit you will gain understanding of the foundations of modern physics and develop research and critical thinking skills.

Assessment summary

Assessment for this unit comprises Astrophysics, Plasma physics and Problem assignments, a literature review project report, and a final exam. 

Final exam: If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator

The final exam is compulsory. Failure to submit will result in an absent fail grade (AF) for the unit.

Assessment criteria

Result name

Mark range

Description

High distinction

85 - 100

  • factual information of an outstanding standard with a sophisticated grasp of the principles and interpretation
  • clear evidence of critical analysis, understanding of experimental design and statistical analysis, integration of knowledge and application to the experimental situation, evidence of originality of thought

Distinction

75 - 84

  • factual information of a superior standard with a sophisticated grasp of the principles and interpretation
  • good evidence of critical analysis, understanding of experimental design and statistical analysis and integration of knowledge; good understanding of the application of knowledge; some evidence of application to the experimental situation

Credit

65 - 74

  • factual information of a high standard, but some information may be incorrect or missing, with sound grasp of the principles and interpretation
  • critical analysis is mainly superficial and relevance of knowledge not always clear, understanding of experimental design and statistical analysis is sufficient and applied to the experimental situation

Pass

50 - 64

  • factual information is of an acceptable standard but basic and contains gaps, errors or inconsistencies/contradictions
  • critical analysis is relatively poor, material may be correct but not entirely relevant; surface understanding of experimental design and statistical analysis with limited application to the experimental situation and limited interpretation

Fail

0 - 49

  • a significant amount of factual information is incorrect
  • misses the point, fundamental misunderstandings evident

For more information see 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.

Academic integrity

The Current Student website  provides information on academic integrity 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 integrity breaches seriously.  

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

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

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. Communicate scientific information appropriately, through written work
  • LO4. Analyse a physical problem in plasma physics and astrophysics and develop a formalism and numerical methods appropriate for solving it
  • LO5. Write a literature review synthesising a topic of current research
  • LO6. Demonstrate a sense of responsibility, ethical behaviour, and independence as a learner and as a scientist

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

GQ2 Critical thinking and problem solving

Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.
