9_7_Astrophysics

NSW Board of Studies - HSC Physics
=Option 9.7 - Astrophysics=

//Contextual Outline:

The wonders of the Universe are revealed through technological advances based on tested principles of physics. Our understanding of the cosmos draws upon models, theories and laws in our endeavour to seek explanations for the myriad of observations made by various instruments at many different wavelengths. Techniques, such as imaging, photometry, astrometry and spectroscopy, allow us to determine many of the properties and characteristics of celestial objects. Continual technical advancement has resulted in a range of devices extending from optical and radio-telescopes on Earth to orbiting telescopes, such as Hipparcos, Chandra and HST.//

//Explanations for events in our spectacular Universe, based on our understandings of the electromagnetic spectrum, allow for insights into the relationships between star formation and evolution (supernovae), and extreme events, such as high gravity environments of a neutron star or black hole.// Taken from Physics Syllabus @ [|Board of Studies]

Student Task - Research one of the topics listed below (given by teacher) and write a brief set of notes for the topic given. These notes will become the notes for your topic. Remeber to acknowledge where information is from. Do not just copy and paste as it is plagerism.

Topics:

2. Careful measurement of a celestial object’s position in the sky (astrometry) may be used to determine its distance** 6. Stars evolve and eventually ‘die’
 * 1. Our understanding of celestial objects depends upon observations made from Earth or from space near the Earth
 * 3. Spectroscopy is a vital tool for astronomers and provides a wealth of information**
 * 4. Photometric measurements can be used for determining distance and comparing objects**
 * 5. The study of binary and variable stars reveals vital information about stars
