10 Credits AUTUMN

Pre-requisites: PHY104

Aims/Description: This module describes how astronomers obtain information about the properties of stars from their atmospheres. On completion, you should be able to appreciate differences between the main 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 have 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.

Restrictions on availability: Only available to students on FF35 (PHYU06), GF15 (MASU21), F3F5 (PHYU11)

Teaching Methods: Lectures, Independent Study
Assessment: Formal Exam, Course work
