Unit description Unit description

This unit covers advanced topics in Astrophysics. For example the physics of fluid dynamics applied to accretion disks and jets in astrophysical objects such as black hole binaries; the physics of star and planet formation; the genesis of the elements; or 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. Strong emphasis is placed on the connection between observations, interpretation and modelling. The scientific method will be used and emphasised as the backbone of all research. Computational techniques in modelling and/or in data analysis will also be used.

Learning in this unit enhances student understanding of global challenges identified by the United Nations Sustainable Development Goals (UNSDGs) Quality Education; Industry, Innovation and Infrastructure

General Assessment Information

In order to pass the unit, you need to obtain a total mark of at least 50%. 

Late Assessment Submission Penalty: Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark of the task) will be applied for each day a written report or presentation assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of ‘0’ will be awarded even if the assessment is submitted. The submission time for all uploaded assessments is 11:55 pm. A 1-hour grace period will be provided to students who experience a technical concern.

For any late submission of time-sensitive tasks, such as scheduled tests/exams, performance assessments/presentations, and/or scheduled practical assessments/labs, please apply for Special Consideration.

Assessments where Late Submissions will be accepted 

Project based assignment – YES, Standard Late Penalty applies 

Special Consideration

The Special Consideration Policy aims to support students who have been impacted by short-term circumstances or events that are serious, unavoidable and significantly disruptive, and which may affect their performance in assessment. If you experience circumstances or events that affect your ability to complete the assessments in this unit on time, please inform the convenor and submit a Special Consideration request through https://connect.mq.edu.au/

A SUMMARY ON THE INDIVIDUAL ASSESSMENTS FOR THIS UNIT:

Project-based Assignment 1 (30%): An assignment focusing on the first half of the unit. It is a project-based assignment involving problem-solving, real-time data analysis, and coding. It assesses the application of numerical methods, interpretation of data, and understanding of astrophysical concepts through practical questions and coding tasks. This project focuses on essential skills not just in astrophysics but in virtually any profession that requires a science degree as a platform.

Project-based Assignment 2 (30%): An assignment focusing on the second half of the unit. It is a project based assignment designed to assess the understanding of astrophysical concepts through practical and conceptual questions. Some of the material will be new to the students, and some will be from content already presented. While students are not expected to grasp every detail immediately, the assignment is structured to challenge their critical thinking and deepen their conceptual understanding of the underlying physics. 

Final Examination (40%): The final examination questions will be in style of short and lengthy quizzes, but answered 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. 

You are expected to present yourself for the final examination at the time and place designated in the University examination timetable. The timetable will generally 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).  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.

If you receive special consideration for the final exam, a supplementary exam will be scheduled after results are released. 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.

Delivery and Resources

The course will be delivered through weekly lectures and tutorial sessions. The unit will be in two parts:

1) Stellar Evolution, Pulsations, and Nucleosynthesis (6 weeks, lecturer Devika Kamath)

2) The physical interpretation of astronomical observations, the physics of the interstellar medium, and the astrophysics of accreting gas in star formation (7 weeks, lecturer Tayyaba Zafar)

Each part will be assessed via a project-based assignment during the term, and will be approximately evenly represented in the final exam.

Changes from Previous Offering

The assessment structure of this unit has been updated to streamline tasks and better reflect student engagement with practical problem-solving and conceptual understanding. The previous four assessment components have been consolidated into three: two major project-based assignments and a final examination. This change ensures a more integrated and applied approach to learning while maintaining alignment with the unit’s learning outcomes.

We value student feedback as a means to continuously enhance our unit offerings. Students are encouraged to provide constructive feedback through surveys, direct communication with teaching staff, or via the FSE Student Experience & Feedback link on the iLearn page. Previous student feedback for this unit was positive, with students expressing satisfaction regarding assessment clarity and the support provided by teaching staff.
