Course Descriptions

ASTR 511 - (3) (O)
Astronomical Techniques

Prerequisites: ASTR 211-212, PHYS 342, 343 or permission of instructor
A survey of modern techniques of radiation measurement, data analysis, and image processing, and their application to astrophysical problems, especially the physical properties of stars and galaxies. Includes relevant laboratory experiments and observations with the departmentís telescopes are included. Students are expected to develop a familiarity with FORTRAN programming and other basic computer skills if they do not already possess them.

ASTR 534 - (3) (E)
Introductory Radio Astronomy

Prerequisite: MATH 225 and PHYS 210
Study of the fundamentals of measuring power and power spectra, antennas, interferometers, and radiometers. Topics include thermal radiation, synchrotron radiation, and line frequency radiation; and radio emission from the planets, sun, flare stars, pulsars, supernovae, interstellar gas, galaxies, and quasi-stellar sources.

ASTR 539, 540 - (3) (IR)
Topical Seminar

Prerequisite: Permission of instructor
A detailed study of a current topic is made by the instructor and the seminar members. Topics vary, and are listed in the Course Offering Directory.

ASTR 542 - (3) (E)
Interstellar Medium

Prerequisite: Permission of instructor
Study of the physics of the interstellar gas and grains, the distribution and dynamics of gas, and cosmic radiation and interstellar magnetic fields.

ASTR 543, 544 - (3) (O)
Stellar Astrophysics

Prerequisite: Permission of instructor
Study of observed properties and physics of stars including radiative transfer; stellar thermodynamics; convection; formation of spectra in atmospheres; equations of stellar structure; nuclear reactions; stellar evolution; and nucleosynthesis. Includes applicable numerical techniques.

ASTR 545 - (3) (E)
High Energy Astrophysics

Prerequisite: Permission of instructor
Introduction to the physics of basic radiation mechanisms and particle acceleration processes which are important in high energy phenomena and space science. Applications to pulsars, active galactic nuclei, radio galaxies, quasars, and supernovae are discussed.

ASTR 546 - (3) (SI)
Binary Stars

Prerequisite: Permission of instructor
Study of the determination of orbital elements, the mass-luminosity-radius relation, formation of binary systems, the Roche model, mass loss, mass transfer, circumstellar material, accretion disks, evolution of close interacting binaries, and some special classes of binaries such as cataclysmic variables, RS CVn binaries, Algol-type binaries, and X-ray binaries.

ASTR 548 - (3) (O)
Evolution of the Universe

Prerequisite: Permission of instructor
Study of the origin and evolution of structure in the universe. Topics include the formation and evolution of galaxies, and tests of the theory based on observations of large-scale structure and the properties of galaxies as a function of look-back time.

ASTR 803 - (3) (SI)
Stellar and Galactic Dynamics

Prerequisite: Knowledge of the methods of advanced calculus and classical mechanics
Study of the types and composition of galaxies; mass distributions and kinematics; general dynamics of stellar systems; Liouville and Boltzmann equations, isolating integrals; encounters, relaxation times; epicyclic stellar orbits; dynamics of interstellar material; observations, hydromagnetic equations; gravitational stability of a disk-shaped galaxy; and spiral structure. Cross-listed as APMA 647.

ASTR 836 - (1) (S)
Current Astronomical Topics

Current research problems are discussed by University of Virginia staff members and guest speakers.

ASTR 849, 850 - (3) (SI)
Advanced Seminar

Subjects of current interest, such as star formation, galaxy evolution, cosmology, etc., are discussed. The topic to be covered appears in the Course Offering Directory each semester.

ASTR 897 - (3-12) (S)
