Recommended preparation: a working knowledge of high school algebra. The
overall architecture of the solar system. Motions of the celestial sphere.
Time and the calendar. Major planets, the earth-moon system, minor planets,
comets. Life in the solar system and beyond. This course is similar to
ASTR BC 1753. You cannot enroll in both courses and receive credit for
both.
Distances to, and fundamental properties of, nearby stars; nucleosynthesis
and stellar evolution; novae and supernovae; galaxies; the structure of the
universe and theories concerning its origin, evolution, and ultimate fate.
You cannot enroll in ASTR C1404 in addition to one of the following ASTR BC1754, ASTR C1420 or ASTR C1836 and received credit for both.
Milestones in the science of cosmology over the past 6000 years. Skylore
and observation in ancient cultures. The twin revolutions of the Greeks:
Pythagoras and Ptolemy. Aristotle, Aquinas, and the Great Chain of Being.
The "scientific revolution": the impersonal and deterministic world-order
of Newton, Laplace, and Kelvin. The erosion of that world-order by
mathematics and experiment in the 20th century (relativity, quantum
physics, dark matter, and the expanding universe). Today's searches for a
new grand order in the Universe, which can cope-or maybe not-with these
blows to yesterday's comfortable wisdom.
Recommended preparation: a working knowledge of high school algebra.
Introduction to astronomy intended primarily for nonscience majors.
Includes the history of astronomy; the apparent motions of the moon, sun,
stars, and planets; gravitation and planetary orbits; the physics of the
earth and its atmosphere; and the exploration of the solar system. This
course is similar to ASTR C1403. You cannot enroll in both courses and
receive credit for both.
Recommended preparation: a working knowledge of high school algebra. A
study of the life cycles of stars, from their birth in cold gas clouds to
their final throes in supernova explosions. The turn-of-the-century
revolution in physics: X-rays, radioactivity, the nuclear atom, and the
quantum theory. Energy production by nuclear fission and fusion, and its
consequences. You cannot enroll in ASTR C1836 in addition to ASTR BC1754 or ASTR C1404 and receive credit for both.
Laboratory for ASTR C1403. Projects include observations with the
department's telescopes, computer simulation, laboratory experiments in
spectroscopy, and the analysis of astronomical data. Lab 1 ASTR C1903 - goes with ASTR BC1753 or ASTR C1403.
Laboratory for ASTR C1404. Projects include use of telescopes,
laboratory experiments in the nature of light, spectroscopy, and the
analysis of astronomical data. Lab 2 ASTR C1904 - goes with ASTR BC1754 or ASTR C1404 (or ASTR C1836).
Prerequisite: a working knowledge of calculus. Corequisite: a course in
calculus-based general physics. First term of a two-term calculus-based
introduction to astronomy and astrophysics. Topics include the physics of
stellar interiors, stellar atmospheres and spectral classifications,
stellar energy generation and nucleosynthesis, supernovae, neutron stars,
white dwarfs, and interacting binary stars.
The standard hot big bang cosmological model and modern observational
results that test it. Topics include the Friedmann equations and the
expansion of the universe, dark matter, dark energy, inflation, primordial
nucleosynthesis, the cosmic microwave background, the formation of
large-scale cosmic structures, and modern cosmological observations.
Introduction to the basic techniques used in obtaining and analyzing
astronomical data. Focus on "ground-based" methods, at optical, infrared,
and ultraviolet wavelengths. Regular use of the telescope facilities atop
the roof of the Pupin Labs, to acquire photometry and spectroscopy of
stars, planets, and nebulae. There will also be apportunity to acquire and
analyze data from National Observatories, and from spacecraft. Given in
alternate years.

Galaxies contain stars, gas dust and (usually) super-massive black holes.
They are found throughout the Universe, traveling through space and
occasionally crashing into each other. This course will look at how these
magnificent systems form and evolved, and what can they tells us about the
formation and evolution of the Universe itself. You cannot enroll in
ASTR C1420 in addition to ASTR BC1754 or ASTR C1404 and receive credit for both.
Recommended preparation: a working knowledge of high school algebra. The
properties of stars, star formation, stellar evolution and nucleosynthesis,
the Milky Way and other galaxies, and the origin and evolution of the
universe. You cannot enroll in ASTR BC1754 in addition to one of the following ASTR C1404, ASTR C1420 or ASTR C1836 and received credit for both.

Prerequisite: a working knowledge of calculus. Corequisite: the second term
of a course in calculus-based general physics. Continuation of
ASTR C2001; these two courses constitute a full year
of calculus-based introduction to astrophysics. Topics include the
structure of our galaxy, the interstellar medium, star clusters, properties
of external galaxies, clusters of galaxies, active galactic nuclei, and
cosmology.
Topics include the physics of stellar, structure, stellar atmospheres,
nucleosynthesis, stellar evolution, interacting binary stars, white dwarfs,
and neutron stars. Offered in alternate years.
The physics and astrophysics of planets, comets, asteroids, natural and
artificial satellites, and pretty much anything in the Solar System -
including the Sun. Detailed study of the Earth's atmosphere and oceans:
circulations, climate, and weather. Orbital dynamics. The emerging
science of extrasolar planets. The origin, evolution, and eventual fate of
planets.
