Notice
As part of Phase 3 of our return to campus plan, most units will now run tutorials, seminars and other small group activities on campus, and most will keep an online version available to those students unable to return or those who choose to continue their studies online.
To check the availability of face-to-face and online activities for your unit, please go to timetable viewer. To check detailed information on unit assessments visit your unit's iLearn space or consult your unit convenor.

Unit description |
Unit description
The first part of this unit covers the physical mechanisms responsible for the generation, absorption and scattering of light in environments as diverse as rarefied nebulae, hot compact stellar atmospheres and distant galaxies. During the second part of the unit the theory of stellar structure and evolution is developed. Students become familiar with spectroscopic observations and the python programming language, and carry out a project using computer models of how stars live and die. |
Information about important academic dates including deadlines for withdrawing from units are available at https://www.mq.edu.au/study/calendar-of-dates
On successful completion of this unit, you will be able to:
The 'estimated time on task' for each assessment item is an estimate of the additional time needed to complete each assessment outside of all scheduled learning activities. These estimates assume that you actively engage with all scheduled learning activities and spend an additional 24 hours of self-led study during the session.
Hurdle tasks
This unit has hurdle requirements, specifying a minimum standard that must be attained in aspects of the unit.
You must obtain a mark of at least 40% in the final exam and laboratory project to be eligible to pass the unit. If your mark in these assessments is between 30% and 39% inclusive, you may be a given a second and final chance to attain the required level of performance. Note that the mark awarded for the second assessment 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.
Supplementary examinations
If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the regular exam period and the start of the next session. 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. You can check the supplementary exam information page on FSE101 in iLearn (bit.ly/FSESupp) for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
If you are given a second opportunity to sit the final examination as a result of failing to meet the minimum mark required, you will be offered that chance during the same supplementary examination period and will be notified of the exact day and time after the publication of final results for the unit.
Late Assessments Policy
The non-examination assessment components should be submitted via iLearn by the due date and time.
The penalty for late submission is deduction of 5% of the possible mark for that item for each 24 hour period (or part) overdue. Assessments will not be accepted for marking if submitted more than 1 week past the due date. Extensions to the due dates for assignments, practical assessments, and project will only be considered if requested with valid reason prior to the due date.
Students anticipating or experiencing difficulties in meeting a deadline should discuss this with one of the lecturers in the first instance, ideally ahead of the deadline, if at all possible. Students should also be familiar with the University's provisions for Special Considerations.

Your lecturers are Associate Professor Richard McDermid and Professor Orsola De Marco.
Lectures will be provided as online videos, posted weekly at the scheduled lecture time.
Weekly tutorials will be on campus, and will be used to go through problem sets, worked examples, and Q&A from lectures.
Lab sessions will be conducted on campus in the Physics and Astronomy computer lab, and will make use of Python Notebooks, running on the Google CoLab environment. Note that labs start in Week 1.
Labs during the first half of the unit will involve using the campus observatory to obtain high-resolution spectra of stars with the Macquarie University Learning and Teaching Spectrograph. This will involve supervised night time observing on campus during weeks 3 and 4. Each student will attend one observing night during this period - please make sure you can attend campus from 8pm-11pm on your allocated night. More details will be provided during the week 1 lab session, and posted on iLearn.
Links to lecture videos, lecture notes, and lab resources, as well as any relevant announcements, will be provided via iLearn. There is no required text, but the course will be closely based on material drawn from one of our favourite books: "An Introduction to Modern Astrophysics" by Carroll and Ostlie.
