P33L/ PHYS3395
ASTRONOMY & COSMOLOGY
(4 Credits) Semester I Level III
Prerequisites : P 14A / PHYS1410 & P 14B / PHYS 1420, and (M 08B/MATH0100, and M 08C/MATH0110 or A-Level Maths or CAPE Maths)
Aims
To allow students to describe the structure, evolution and behaviour of astronomical objects and of the universe.
Objectives
- To explain the basic physics of stars and of celestial mechanics
- To identify and describe the main features of the content and structure of the solar system, the galaxy and the universe using traditional methods
- To describe the methods used in astronomical measurements and deduction of results
- To describe the standard stellar structures and evolution
- To explain simple cosmological models and the observations on which they are based
- To describe the basics of the standard big bang theory of the evolution of the universe
