Unit description 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 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 dynamics of gas flows in Astrophysical environments (including magnetic fields, shocks and viscosity). Applications to disks and jets will be discussed in particular.
  • Solve problems in real-time during class tutorials, and demonstrate solutions to peers
  • Learn to communicate complex physical concepts in writing and orally.
  • Learn how to exploit computers to solve astrophysical problems.

General Assessment Information

In order to pass the unit, you need to obtain a total mark of at least 50%, as well as a mark of at least 40% in the final exam.

Oral assessment: On 4 separate weeks the students will be given a week to read a set of notes and book pages. In order to digest the material the students are asked to print and annotate the pages, including answering a questionnaire and to be prepared to explain any part of the material to their peers in class during a 2 hour long round table discussion. Part of the material will be new to the students and part will be from content already presented. It is not expected that students understand everything they read. However, it is expected that they are able to present questions about any aspects that they do not fully comprehend and that these questions be in the context of those concepts that they do understand.  The ability to explain any concept in a clear fashion and according to some pre-agreed specification (level of depth, time constraints, etc.) is a key skill to be mastered by any science student. This is why this assessment task is part of this unit.

This assessment task also allows the lecturer to "flip" part of the unit. The oral session where the students are presenting and discussing material that has not yet been presented by the lecturer, will allow the lecture time to be a far more interesting and in depth discussion session, rather than board presentation. The lecturer will be there to consolidate concepts and stimulate a deeper understanding. 

Assignments: four exam style assignments will be given to prepare students for the type of questions they might be getting in the final exam and to test their general understanding and their problem solving skills. Programming a computer to answer questions that are not simple to answer in any other way is an essential skill not just in Astrophysics but in any job that require a science degree as a platform. In part of each assignment the student will write short computer codes to answer questions. 

The final examination will be three hours long duration plus ten minutes reading time.  The final examination is similar to the theoretical side of the Assignments in style, but is carried out under controlled conditions and without the help of books. 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.  

The final examination is a hurdle requirement. You must obtain a mark of at least 40% in the final exam to be eligible to pass the unit. If your mark in the final examination is between 30% and 39% inclusive, you may be a given a second and final chance to attain the required level of performance; the mark awarded for the second exam towards your final unit mark will be capped at 40%, and you will be allowed to sit the second exam only if this mark would be sufficient to pass the unit overall. If you receive special consideration for the final exam, a supplementary exam will be scheduled after results are released. Please see FSE101 in iLearn for dates. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination. Second chance exams for hurdle assessments will also be scheduled in this period.

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.

Changes from Previous Offering

Modifications to the syllabus this year will be:

1) A slightly shorter section on stellar pulsations in the first part of the unit (lecturer Devika Kamath)

2) Slightly reduced emphasis on star formation with increased emphasis on accretion in general and disk formation and evolution.  (lecturer Orsola De Marco)

Assessment was simplified as follows:

1) The class participation item was eliminated.

2) The presentation assessment substituted with 4 oral/presentation assessments.

3) The computer assessment was integrated into 4 regular assignments.

4) The short answer assessment task (class flip) was integrated into the oral presentation.
