SELT Survey Results

This course provides an introduction to stellar structure, evolution, and atmospheres. It covers the basic physical processes that govern the behaviour of stars, including hydrostatic equilibrium, thermal balance, nuclear energy generation, and radiation transport, the application of these principles to modeling the life cycle of stars from birth to the main sequence to death, and the development of tools to deduce stars' physical properties from the light they emit.
This course can be taken as an HPO, please discuss with course convener.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Explain the concepts of hydrostatic balance, equations of state for stellar matter, transfer of heat through stars, stellar nucleosynthesis, and radiation transport, and perform calculations using these concepts;
  2. Calculate the internal structures of stars at a variety of levels of approximation;
  3. Describe the life cycles of stars from birth to death, and how these cycles depend on stellar mass;
  4. Explain the basic theory of stellar spectra, and use this theory to interpret the observed spectra of stars;
  5. Work effectively as part of a group.

Policies

ANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:

Assessment Requirements

The ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website Students may choose not to submit assessment items through Turnitin. In this instance you will be required to submit, alongside the assessment item itself, hard copies of all references included in the assessment item.

Moderation of Assessment

Marks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.

Examination(s)

There will be a final written exam at the end of the semester with questions that cover all topics covered in the course. Value: 40%. Students will be assessed on their knowledge and problem-solving skills they acquired of the course material.


Please note, that where a date range is used in the Assessment Summary in relation to exams, the due date and return date for mid-semester exams indicate the approximate timeframe in which the exam will be held; the due and return date for end of semester exams indicate the approximate timeframe in which the exam will be held and the date official end of Semester results are released on ISIS.
