This section of The Science Vault is a collection of notes by an IB Higher Level Physics class of November 2006. It concerns the Option F - Astrophysics of the syallbus. This section has two ways of nagivation; by syllabus points (below and left), and by what was felt to be a more natural method, where similar topics were grouped together (below).

This section is still under construction, so please be patient, as not all the links may work. Thank you!

Introduction to the Universe – Universe? What universe?

The Solar System – At the unfashionable west end of the galaxy

Stellar Objects – Nuts, bolts and building blocks

Stellar Sizes – Big, bigger and infinite

Stellar Radiation – What shines… and what doesn’t

Luminosity - Hot ot not!

Black Body Radiation – Black body, hot body

Wien's law and the Stefan-Boltzmann law

Stellar Spectra – Colours really do tell

Stellar Types – Hot and not

Star Types – Bright & hot, or cold & dark

Stellar Evolution – How to Make your own star

Hertzsprung-Russell diagram – On the charts…

Stellar Distances – Shooting for the stars

Parallax Method – Angling for the stars

Brightness - Starlight, star bright

Spectroscopic Method – Bright, near and far

Cepheid Variables – Candle in the window

Cosmology – Life, the universe and everything

Olbers’ Paradox – Where Newton went wrong

Hubble’s Law – It’s getting bigger!

The Big Bang – A conical bath backwards

Galactic types and motion - Turn, turn, turn ...
