You should understand the following words and concepts that describe properties
of the Sun that can be observed directly.
- luminosity
- solar constant
sunspot
- sunspot cycle
- solar wind
- solar flare
- helioseismology
From these observations and application of physics understood from experiments
on Earth, we have been able to construct a model of the Sun and its interior
that fits various observations, some of which are discussed in class.
- standard solar model
- solar structure
- solar core
- radiation zone
- convection zone
- photosphere
- chromosphere
- corona
- mass-energy relation
- nuclear fusion
- proton-proton chain
- neutrino
- solar neutrino
This list covers the vocabulary added in chapter 9. Other concepts from
earlier chapters are also needed to understand the basics of how the
Sun works, and how we observe it -- especially the properties of
atoms, molecules and photons that explian the properties of spectra
(blackbody, absorption and emission).
