PHY305 - Stellar Atmospheres
This module describes how astronomers obtain information about the properties of stars from their atmospheres. Students should be able to appreciate differences between the main stellar spectral types, understand how the interaction of radiation with matter affects the appearance of a stellar atmosphere, including the major sources of opacity. You will develop a knowledge of the formation of spectral lines, line broadening mechanisms, plus an appreciation of the use of stellar continua and lines as atmospheric diagnostics. The outer Solar atmosphere will also be discussed, together with outflows from late and early type stars.
