OLET1638: Astronomy: from Stars to Black Holes

This unit of study explores the lives of the stars, leading some to explosive ends and the formation of a black hole. You will learn about the life cycle of a star from its birth in the interstellar medium to its fate as a stellar remnant - as a white dwarf, neutron star or perhaps a black hole. You will work with simulations to gain an appreciation and understanding of the methodology and techniques of modern astronomy, especially astronomical spectroscopy that allows us to measure the composition, physical state and motion of the stars. These measurements also reveal the extreme properties of stellar remnants. More recently, observations of gravitational waves have opened a new window on the universe, allowing us to study the merger of neutron stars. Our study of spectroscopic and gravitational wave observations of extreme environments will clearly illustrate how modern astronomy depends on advancing technology leading to new instrumentation and observational capabilities. The unit also includes opportunities for day and night observing sessions.

  • Embedded quizzes: Comprehension of the online material will be tested by brief, automatically marked, multiple choice mini-quizzes. These are used to help you step systematically through the Canvas pages.
  • Mastering Astronomy quizzes: MA quizzes at the end of each week are designed to build your understanding of aspects of the material with more complex questions incorporating hints, feedback and multiple, automatically marked attempts.
  • Tutorials: Students individually submit results from the weekly tutorial exercise, many of which use real astronomical data.
  • Night Sky worksheet: This worksheet aims to show how and where the astronomical objects described in this unit are visible in the night sky. It is intended to sit in parallel with the optional Night Sky observing session.
  • Final examination: Understanding of key concepts of the unit is tested in an online exam comprised of short answer questions. See the Sample Exam papers in the Canvas pages for this unit for an accurate indication of the exam structure.

Detailed information for each assessment can be found on Canvas.

Note that attempting the final examination is required for a pass in this unit.

If you miss the final exam for any reason you should submit an application for Special Consideration to request a replacement exam in the same format.

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.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014(Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

85 - 100

Excellent understanding demonstarted in quizzes and the final exam; thorough understanding of tutorial materials; on-time completion of all aspects of the unit.

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.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Standard University late penalties apply. As an example, on a Tutorial submission given a mark of 4/5, the penalty would be 0.25 marks if submitted up to 24 hours late, resulting in a final mark of 3.75/5. If the assignment is submitted 6 days late, the penalty would be 1.5 marks and the final mark would be 2.5/5. If you have difficulty submitting an assessment on time, you should submit an application for Special Consideration. A Simple Extension of up to two working days negotiated with the unit coordinator is occasionally an alternative. However, in this unit, Simple Extensions will only rarely be granted since justifiable reasons for extension should usually be eligible for Special Consideration.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, 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 dishonesty or plagiarism seriously.

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

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 2 credit point unit, this equates to roughly 40-50 hours of student effort in total.

Required readings

All readings for this unit can be accessed on the Canvas site for this unit.

Other resources

Extensive and reliable astronomy information is available on-line, beyond the materials and links presented on the Canvas pages.  Introductory astronomy textbooks at a suitable level (similar to the online text linked in the canvas pages) are available in the SciTech library. For example, a book we have used in the past is The Cosmic Perspective, Jeffrey O. Bennett (various editions).

Be aware that astronomy is a rapidly advancing field and, while all the basic information will be correct in older books and give you a good background, the latest information and perspectives that we embed in this unit may be missing.

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. Compare and contrast the basic observable properties of stars and how they are measured
  • LO2. Summarise the birth and evolutionary history of stars of various masses
  • LO3. Discuss the indigenous astronomy context for modern stellar astronomy
  • LO4. Carry out simulations to illustrate how spectra are used to determine properties of stars
  • LO5. Compare and contrast the characteristics of exotic stellar remnants - white dwarfs, neutron stars or black holes
  • LO6. Outline the significance of changing technology, in particular spectroscopy and gravitational wave observations, in observation of stars and stellar remnants
  • LO7. Carry out simple observations of the planets and stars using an optical telescope to illustrate the central role of observation in astronomy.

We welcome comments on all aspects of this unit. You should feel free to talk to your lecturers, tutors or the Unit Coordinator A/Prof. John O’Byrne at any time. There is also a formal opportunity for feedback via the USS questionnaire for this unit, available online towards the end of semester. As a result of student feedback and other initiatives there have been a number of changes in this unit recent years. This year: - one set of quizzes has been dropped to reduce the assessment load - the Night Sky worksheet has been formalised in parallel with making the Observing session optional. Changes carried on from last year include: - Times for submission of quizzes and tutorials reduced to encourage students to 'keep up' - and allow timely emails when they don't. - The exam date moved to shortly after the face-to-face component of the unit finishes, allowing students to sit the exam when the content is fresh in their minds.
