This course unit detail provides the framework for delivery in 21/22 and may be subject to change due to any additional Covid-19 impact. Please see Blackboard / course unit related emails for any further updates
On completion successful students will be able to:
- give a qualitative description of the Solar System and to know how the current picture emerged.
- apply dynamical principles to understand phenomena such as tides and orbits in the Solar System.
- make simple orbit calculations, based on energy and angular momentum conservation. Understand the basis of Kepler's laws and the Virial Theorem.
- know what may be deduced about the Sun by considering it as a black body and body in hydrostatic equilibrium.
- explain the basic principles behind the energy generation in the Sun.
- gain some knowledge of planetary atmospheres and to understand the origin of the Earth's greenhouse effect.
- gain some simple knowledge of the internal constitution of the planets.
- know how planetary ring systems may be formed.
- know the consequences of impacts in the Solar System.
- understand in outline how the Solar System is thought to have formed and evolved.
1. Overview of the Solar System
General description and inventory. Coordinates and time keeping. Date & time in the solar system
Kepler's laws; energy; orbits; space travel; tides.
3. The Sun
Plasma and magnetism; nuclear energy and solar neutrinos; helioseismology.
4. Planetary atmospheres
Origins; equilibrium temperatures; pressure and temperature profiles; atmospheric escape; composition; clouds; climate.
5. Planetary surfaces
Impact craters. Isotope dating.
6. Planetary interiors
Moments of inertia; seismology; volcanoes & plate tectonics; heating & cooling; magnetic fields.
7. The formation of the solar system
Interstellar origins; planet formation; future evolution.
Students will receive feedback on a number of optional problem sheets.There will also be weekly quizzes to provide feedback on understanding.
