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. |
Important Academic Dates
Information about important academic dates including deadlines for withdrawing from units are available at https://www.mq.edu.au/study/calendar-of-dates
Learning Outcomes
On successful completion of this unit, you will be able to:
- ULO1: discuss principles and difficulties of observational methods that allow us to interpret the physical characteristics of an astronomical object based on the light we receive from it.
- ULO2: demonstrate knowledge of the way radiation interacts with matter in different astrophysical environments through solving radiative transfer problems.
- ULO3: describe the internal structure of our Sun and stars other than the Sun, and explain the key observational properties of different types of stars.
- ULO4: apply the equations of stellar structure and the simplifications that lead to polytropic stellar models.
- ULO5: explain the processes and physics involved in stellar evolution, including the processes that bring about stellar death.
- ULO6: apply computational techniques to model physical phenomena in different astrophysical environments using the Unix environment and elements of the python computing language.
- ULO7: design, conduct, analyse and report on observational experiments related to measuring the radiation from stars, galaxies and other astronomical objects in order to determine their properties.
General Assessment Information
Project: a computational project based on calculating and analysing the structure and evolution of a given star. It is almost entirely carried out in the computer lab sessions in the second part of the semester. The Project report will be due one week after the last PC Lab class.
Assignments: there will be 4 assignments, 2 per each part of the unit. They will be approximately evenly scattered.
Observational task: Students will observe a number of targets using MQ Observatory. They will also analyse their observational data (in case of bad weather, data will be provided). A small component of this observational task will be conducted in the laboratory. The students will have to carry out some tasks related to constructing an astronomical spectrograph. A report of this activity will be due after the semester break.
A standard, 3-hour, written exam (plus 10 min reading time) will be given in the university examination period.
