Unit description
This unit covers the fundamental physics of celestial objects such as stars and galaxies. It starts with the physics of fluid dynamics and the interaction of matter with light; these concepts are then used to describe the interstellar medium, including star formation and the stellar feedback of energy and new elements. The unit concludes with a discussion of galactic formation and evolution from the standpoints of interstellar gas and stellar populations. Observations of real celestial objects are used throughout the unit as examples of the processes we need to explain.
Throughout the unit strong emphasis is placed on the connection between observations and interpretation. The student will gain an understanding of how different types of observations (imaging, spectroscopy, multi-wavelength approaches, survey approaches) can allow us to gain insight into specific astrophysical situations and how these observations can be interpreted in the light of theory. The scientific method will be used and emphasised as the backbone of all research and its stages underlined during class and all the activities.

Learning Outcomes
On successful completion of this unit, you will be able to:
- Understand the role of gas in the lives of galaxies, with respect to observations and theory
- Understand the role of magnetic fields in the dynamics of interstellar gas and the role they play in star formation.
- Understand the basics of binary interactions
- Understand stellar pulsations and role this plays in stellar evolution and mass loss
- Understand the synthesis of elements in stars and their observed chemical abundances
- Understand the role of accretion of gas onto stars, both in star formation and binary interactions.
- Solve problems in real-time during class tutorials, and demonstrate solutions to peers
Assessment Tasks
| Name | Weighting | Hurdle | Due |
|---|---|---|---|
| Assignment Tasks During Term | 50% | No | Approx. weeks 3, 5, 7, 10, 12 |
| Final Exam | 50% | No | University Exam Period |
Assignment Tasks During Term
Due: Approx. weeks 3, 5, 7, 10, 12
Weighting: 50%
Five assessed problem sets will be given during the semester, each worth 10% of the final grade. Additional problem sets may be provided by the lecturer for the purpose of self-assessment. Tutorial sessions will be used to review problem sets, and students are expected to be able to demonstrate their solutions on the whiteboard in front of the class.
The assignments are an integral part of the unit and aid your understanding of the material. Extensions will only be considered if requested with valid reasons prior to the due date, and the penalty for late submission of the assignments is the subtraction of 5% of the final assignment grade for every day of delay. The assignment can not be turned in more than 1 week past the official due date.
On successful completion you will be able to:
- Understand the role of gas in the lives of galaxies, with respect to observations and theory
- Understand the role of magnetic fields in the dynamics of interstellar gas and the role they play in star formation.
- Understand the basics of binary interactions
- Understand stellar pulsations and role this plays in stellar evolution and mass loss
- Understand the synthesis of elements in stars and their observed chemical abundances
- Understand the role of accretion of gas onto stars, both in star formation and binary interactions.
- Solve problems in real-time during class tutorials, and demonstrate solutions to peers
Final Exam
Due: University Exam Period
Weighting: 50%
The final examination will be of three hours duration plus ten minutes reading time. Battery or solar powered calculators which do not have a full alphabet on the keyboard will be allowed into the examination. Calculators with text retrieval are not permitted for the final examination.
You are expected to present yourself for the final examination at the time and place designated in the University examination timetable (http://www.timetables.mq.edu.au/). The timetable will be available in draft form approximately eight weeks before the commencement of examinations and in final form approximately four weeks before the commencement of examinations.
The only exception to not sitting the examination at the designated time is because of documented illness or unavoidable disruption. In these circumstances you may wish to apply for Special Consideration (see ‘Special Consideration’ in this Guide). If a supplementary examination is granted as a result of the special consideration process the examination will be scheduled after the conclusion of the official examination period. You are advised that it is the policy of the University not to set early examinations for individuals or groups of students. All students are expected to ensure that they are available until the end of the teaching semester, i.e. the final day of the examination period.
On successful completion you will be able to:
- Understand the role of gas in the lives of galaxies, with respect to observations and theory
- Understand the role of magnetic fields in the dynamics of interstellar gas and the role they play in star formation.
- Understand the basics of binary interactions
- Understand stellar pulsations and role this plays in stellar evolution and mass loss
- Understand the synthesis of elements in stars and their observed chemical abundances
- Understand the role of accretion of gas onto stars, both in star formation and binary interactions.
Delivery and Resources
The course will be delivered through weekly lectures and tutorial sessions. The unit will cover four parts:
1) Astrophysics of the Interstellar Medium (3 weeks, lecturer Joanne Dawson)
2) Astrophysics of star formation, including the effects of magnetic fields (3 weeks, lecturer Orsola De Marco)
3) Stellar Pulsations and Stellar Nucleosynthesis (5 weeks, lecturer Devika Kamath)
4) Astrophysics of accreting gas in star formation and binary interactions (2 weeks, lecturer Orsola De Marco)
Each part will be assessed via problem sets during the term, and will be approximately proportionally represented in the final exam.
