Objectives At the completion of this subject a student should know the main concepts of positional astronomy and be able to solve problems involving the celestial sphere, apparent motion, coordinate systems, time and navigation; understand, be aware of the nomenclature, and be able to solve simple problems concerning the orbits of the planets and satellites, including tides; understand the various telescope systems used in modern astronomy, together with their detector systems; have an appreciation of the manner in which observational measurements are made; understand the general scale, geometry and mechanics of the solar system; know the general features of the planets of the solar system and their satellites; be able to give an account of various theories of the solar system formation.
Synopsis This is an introduction to astrophysics, in which physical ideas gained in first year are developed and used to understand how data from the cosmos are obtained and interpreted. Laboratory work introduces experimental techniques and illustrates and extends the lecture material. Students may undertake their own astronomical observations. Topics covered are practical astronomy (eg coordinate systems, time, orbits); the solar system (including physical properties, origin theories); observational techniques (including telescopes, detectors, space-based systems).
Assessment Examination (3 hours): 67% + Laboratory work: 33%
