| Planetary Astronomy has re-emerged as a major
area
of astronomical research, and some knowledge of this
area is essential to a balanced astronomical education.
Besides the many discoveries made from ground-based and
earth-orbiting telescopes, space missions to solar-system
objects contribute to the discoveries and the excitement.
And the solar system serves as "ground truth" for other
planetary systems.
Progress and discoveries, many since approximately 1990, have introduced new words or phrases into our astronomical vocabulary: escape hatch; Yarkovsky effect; Kuiper Belt Object (KBO); heliospheric current sheet (HCS); disconnection event (DE); magnetic reconnection; comet D/Shoemaker-Levy 9; impacts on Jupiter; Io auroras; sodium tail; Vesta chips; zonal winds; planetary weather; water on Mars; amorphous water; standard method; binary asteroids; Chicxulub crater; and Near-Earth Objects. Astr 427 provides an overview of solar-system research and these words or phrases will be explained. |

The level is intended for upper-division undergraduates and beginning graduate students. The coverage will be partly qualitative and partly quantitative. For the quantitative part, the student will need algebra, trigonometry, calculus, and general physics. An introductory astronomy course would be helpful, but is not required. Note that the physical explanations will be developed starting from a general physics level.

The major topics currently planned are: basic orbits,
including resonances and chaotic behavior; Mars--atmosphere
and surface; giant planets-- atmospheres and interiors;
solar wind--origin, structure, and interactions with the
earth's magnetosphere, Jupiter, and comets; zodiacal light;
rings with emphasis on Saturn; asteroids; comets; solar-system
collisions; meteors and meteorites; and solar-system origin.
Course grade will be based on class participation (10%),
mid-term exam (30%), Text: The Planetary System, 3rd Ed. by Morrison &
Owen, Addison-Wesley(2003). Other sources including the recent literature and unpublished papers will also be used. |
