651-4013-00L | Potential Field Theory | 3 credits | 2G | A. Khan, A. Jackson | |
Abstract | The course will guide students in learning about the capabilities and limitations of potential field data, namely gravity and magnetic measurements as collected by industry, in determining geological sources. It will follow a mathematical approach, and students will learn to apply mathematical strategies to generate quantitative answers to geophysical questions. | ||||

651-4228-00L | Topics in Planetary Sciences | 2 credits | 2G | M. Schönbächler, H. Busemann, A. Khan, P. Tackley | |
Abstract | The course will be based on reading of research papers. Themes can vary from year to year and will cover planetary geophysics, geochemistry and the dynamical evolution of planetary bodies. The format of the course will be centered on short lectures introducing a theme, followed by a presentation of one or more papers by a student or group of students and an open discussion of the topic. | ||||
Objective | The goal of the course is discuss topics in planetary sciences, which were not covered in the general planetary science courses. The course also aims at training the student's ability to critically evaluate research papers, to summarize the findings concisely in an oral presentation, and to discuss these in the group. | ||||
Content | Themes will vary from year to year and suggestions from students are welcome. Possible topics include: - Formation of the terrestrial planets - Evolution of terrestrial bodies (Mercury, Venus, Moon, Mars, Vesta) and icy moons (Ganymede, Callisto, Enceladus) - Active asteroids/main-belt comets - Geophysical and geochemical exploration of planetary bodies (e.g., remote sensing, meteorite studies, seismology, electromagnetic sounding, gravity, and geodetic). | ||||
Prerequisites / Notice | The students are expected to have passed either course 651-4010-00L Planetary Physics and Chemistry or course 651-4227-00L Planetary Geochemistry. |
