Courses in Astronomy (Division 326)

Introductory Courses and Courses for Non-Concentrators.

Astronomy 101/111 discusses our explorations of the solar system. Astronomy 102/112 deal with stars and the rest of the Universe beyond the solar system. Students in Astronomy 101 and 102 attend a weekly discussion section. Students in Astronomy 111 and 112 actively participate in a laboratory which meets in the evening each week. Astronomy 130 covers selected topics from the whole field of astronomy. None of these courses is a prerequisite for any of the others. High school mathematics through plane geometry is useful. All students in each course will have opportunities for a planetarium visit and for evening observations with the telescopes mounted on Angell Hall.

Astronomy 111 has laboratory sections. Astronomy 101 has discussion sections. Course requirements include homework observations, six short quizzes, two midterms and a final examination. Laboratory sections include observations with telescopes. A planetarium visit will be arranged. (Sears)

Section 006. Lectures (the same for both Astronomy 101 and 111) deal with the beginnings of astronomy, motions of bodies in the solar system, properties of light and atoms, the Sun, the Earth, the Moon, individual planets and satellites, comets and meteors, and the origin of the solar system and life. Elementary concepts of physics, chemistry, and geology are introduced in order to elucidate the new understanding of the solar system made possible by the space program. Emphasis is placed on an understanding of the composition, nature, and history of matter in the solar system. Special attention is devoted to terrestrial, lunar and meteoric rock samples, as well as surface land features on terrestrial planets. Astronomy 101 has discussion sections. Astronomy 111 has laboratory sections. Course requirements include homework observations and exercises, two one-hour quizzes, and a final examination. Observations with telescopes and a planetarium visit will be arranged. Textbook: Exploration of the Solar System, by W.J. Kaufman, III (Macmillan, 1978). (Cowley)

112. Introductory Astronomy: Stars, Galaxies, and the Universe. No credit is granted to those who have completed 102 or 130. (4). (NS).
Section 001.
This course is intended primarily for non-science majors and it is not necessary for a student in it to have taken Astro 101 or 111 as a pre-requisite. The subject of the course is the astronomical description of the Universe beyond the solar system. We will examine the properties of stars, of the material in space between the stars, and of the galaxies, and will give special attention to current scientific views about the nature and origin of the Universe. There will be two midterm examinations and a final examination. Astronomy l02 students will have homework connected with their discussion sections; Astronomy 112 students will work on laboratory exercises. The discussion sections and laboratory sections will include planetarium demonstrations and observing sessions with the telescopes. Textbook: Exploration of the Universe (fourth edition) by G. Abell. (Teske)

Section 006. Lectures are the same for Astronomy 102 and 112. This course treats modern ideas concerning the origin and evolution of stars, galaxies, and of the Universe as a whole. The lectures emphasize current knowledge of the formation and evolution of stars toward their ultimate destiny as white dwarfs, neutron stars, or black holes. The course will outline the evidence that the Universe is currently expanding from a hot dense phase in the distant past toward a fate that is accessible to observation. Specific objects such as supernovae, quasars, and galaxies are also examined. Course work includes assigned reading, short quizzes, midterm and final examinations, and section meetings. Astronomy 112 students have evening laboratory and observation periods every other week, and daytime discussions in alternative weeks. Astronomy 102 has only discussion sections. (Kirschner)

130. Explorations in Astronomy. No credit is granted to those who have completed 101, 102, 111, or 112. (4). (NS).

This course covers selected topics concerning the stars, the galaxy, and the universe. Some of the subjects discussed are: the results of the space program, the life history of stars, interstellar nebulae, pulsars, black holes, normal and peculiar galaxies, quasars, and the evolution of the universe. There are four lectures per week and observations with telescopes and a planetarium visit will be arranged.

221. General Astronomy: The Solar System. Prior or concurrent election of Math. 115. No credit is granted to those who have completed 101, 111, or 130. (4). (NS).

Astronomy 221-222 is a two-term introductory sequence intended primarily for students in the sciences and engineering. In the Fall Term, Astronomy 221 deals with the astronomy and physics of the solar system. Topics covered include: (1) principles of orbit theory; (2) interior structure, surface features and atmospheres of the planets; (3) the minor constituents of the solar system; (4) the sun. Laboratory work will include observations with the telescopes atop Angell Hall, experiments and discussions. Homework problems are assigned almost weekly. There will be a final, two one-hour examinations, and periodic quizzes. (Aller)

261/NOEP 301. Navigation. (2). (Excl).

The purpose of this course is to educate students in all aspects of marine navigation, from getting a vessel underway from port through open ocean navigation using both celestial and electronic means. The content of the course is divided into three major areas. The first section focuses on piloting, emphasizing the safe navigation of vessels in coastal waters. This section provides an introduction to navigational instruments and aids to navigation. The second section concerns celestial navigation, the ability to determine position through observation of celestial bodies. Students learn how to determine position based on the use of the sextant and various almanacs and mathematical tables. The third section of the course considers electronic navigation and the maritime law covering the movement of sail and power-driven vessels. The course consists of two ninety-minute lectures a week. Grading is done on the basis of homework, quizzes, and examinations. The primary textbooks for the course are Marine Navigation I and Marine Navigation II by Richard R. Hobbs and are available on loan from the NOEP. (Nelson)

321. Solar-Terrestrial Relations. Four credits of astronomy. (2). (NS).

For students who wish to learn more about our sun, its activity cycle, and the influence on our earth. Objectives: To work toward a better understanding of the many phenomena observed from ground as well as from satellites. The physical processes involved will be sketched using a minimum of mathematics. Mathematics background is advantageous but not required. Topics as follows: The Quiet Sun: nuclear energy sources in the interior; the surface layers; interplanetary space. The Earth and its Immediate Surroundings: atmosphere, ionosphere, radiation belts. Solar Activity: sunspots, magnetic fields, plages, prominences, corona, flares; the 11/22 year cycle; high-energy radiation and particle events; changes in the earth's atmosphere caused by solar events; possible long term effects. Instruction by lectures with slides and occasional movies. Exercises on interpretation of observations. Evaluation of participation in discussions, two or three tests, final exam, or term paper. (Elste)

421. Advanced General Astronomy. Phys. 140 and 240 and Math. 116, or the equivalent; or permission of instructor. (3). (NS).

50% of the course will be based on independent reading of William K. Hartmann's Moons and Planets (second edition). The remaining 50% of the course will be based on material presented in the lectures. This is divided into 3 parts. Part I deals with the mechanics of the solar system, and covers topics such as the two-body problem, N-body relations, the virial theorem, potential about an oblate spheroid, equations of rigid-body motion, etc. Part II treats geochemistry and cosmochemistry with special reference to the solar system. Included topics are fundamental principles of thermodynamics and chemical reactions, meteorites, geochemical classification of the elements, models of the solar nebula, condensation sequences from the solar nebula and the composition of planets. Part III deals with planetary structure, and emphasizes comparative planetology of the moon and terrestrial planets. The level of difficulty will be similar to that of junior and senior courses in physics and chemistry. (Cowley)
