Module Objective: To introduce students to a variety of topics in astronomy and special relativity.
Module Content: Celestial coordinate systems, parallax distance determination, the virial theorem; orbits, tidal forces, formation and structure of the solar system, blackbody radiation; Doppler shifts of spectral lines, special relativity & astrophysical applications (cosmic rays, astrophysical jets).
Learning Outcomes: On successful completion of this module, students should be able to:
- Show familiarity with equatorial celestial coordinates, parallax distance determination and the magnitude brightness scale,
- know the virial theorem and how to apply it, including an ability to identify situations where it is not applicable,
- Show familiarity with Newton's shell theorem and how to apply it in astrophysical problems,
- Show familiarity with the properties of elliptical, parabolic and hyperbolic orbits and their relationship to the total energy and angular momentum of an orbiting body,
- Explain the origin of tidal forces and their various consequences for orbiting bodies,
- Demonstrate knowledge of the basic properties of the solar system and theories for its formation and structure,
- Demonstrate an understanding of the properties of blackbody radiation and the distinction between thermal/non-thermal radiation,
- Explain the origin of spectral line emission, Doppler line shifts and line-broadening mechanisms,.
