An overview of the physical principles and observational phenomenology describing stellar atmospheres and stellar evolution. Topics covered include: atmospheric temperature structure and line formation; atmosphere models and spectral type determination; observational (spectral) diagnostics of stellar masses, abundances, ages and evolutionary states; and a survey of contemporary topics in star formation and pre- and post-main sequence stellar evolution, with emphasis on the physical processes governing stellar accretion, mass loss, and the effects of binary companions on these processes.

This course provides an understanding and appreciation of the fundamental science goals driving the development of contemporary astronomical imaging systems and the basic principles and concepts underlying those systems. Students will investigate the world's most powerful telescopes and cameras presently operating in the realm of human vision, as well as systems that image the “invisible”, by tapping the infrared, X-ray, and radio regimes of the electromagnetic spectrum. Laboratory exercises familiarize students with basic visualization, manipulation, and measurement of real astronomical images (drawn from major-facility archives) that span these regimes. Students will also get a glimpse of the future of astronomical imaging. This course satisfies a General Education elective requirement in the areas of natural science inquiry, scientific principles, or science/math literacy. Math proficiency at college algebra level is required.

    Scientists release new insight about Southern Ring Nebula

    Planetary nebulae have been studied for centuries, but astronomers are getting new looks and a better understanding of the structures and compositions of these gaseous remnants of dying stars thanks to the ability to study objects at multiple wavelengths and dimensions.
