OLET1638: Astronomy: from Stars to Black Holes

Intensive March - April, 2024 [Block mode] - Camperdown/Darlington, Sydney

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 night observing sessions.

Early feedback task

This unit includes an early feedback task, designed to give you feedback prior to the census date for this unit. Details are provided in the Canvas site and your result will be recorded in your Marks page. It is important that you actively engage with this task so that the University can support you to be successful in this unit.

Assessment summary

  • 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.  These are (hopefully) a significant learning exercise, as well as a major contribution to marks in the unit.
  • Optional Observing: This is an optional group activity to use optical telescopes on the roof of the Sydney Nanoscience Hub (SNH) to view the night sky.  There is no marked assessment associated with this activity.
  • Final examination: Understanding of key concepts of the unit is tested in an on-campus 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.

For more information see guide to grades.

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 five working days on Assignments is also available through the special consideration portal, or for Quizzes may be negotiated with the unit coordinator. However, in this unit, negotiated Simple Extensions will only rarely be granted since justifiable reasons for extension should usually be eligible for Special Consideration.

Academic integrity

The Current Student website provides information on academic integrity 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 integrity breaches seriously.

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

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Support for students

The Support for Students Policy 2023 reflects the University’s commitment to supporting students in their academic journey and making the University safe for students. It is important that you read and understand this policy so that you are familiar with the range of support services available to you and understand how to engage with them.

The University uses email as its primary source of communication with students who need support under the Support for Students Policy 2023. Make sure you check your University email regularly and respond to any communications received from the University.

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.

This section outlines changes made to this unit following staff and student reviews.

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. This semester we are making some significant changes to reduce the number of formal assessment tasks - dropping marks on mini-quizzes and making all Observing related tasks optional. In addition, a significant change is the introduction University-wide of an early assessment task to ensure student engagement early in the semester. In this unit, that is the first Mastering Astronomy quiz.
