ASTRO 3301 Exoplanets and Planetary Systems

More than five thousand planets circling other stars have been discovered over the past two decades, and many more discoveries are sure to come. With the recent launch of the James Webb Space Telescope (Dec 2021) astronomers will be able to probe the atmosphere of potential Earth-like planets for the first time.How are these discoveries made and what are the properties of these exoplanets and their systems? How exotic can exoplanets to be? Would you survive on them? Is our solar system a typical planetary system or something unusual? How common are planets like Earth? How can we determine whether exoplanets can host life, or do host life? These and other issues related to planetary formation and evolution will be discussed in the course.

ASTRO 4445 Introduction to General Relativity

One-semester introduction to general relativity that develops the essential structure and phenomenology of the theory without requiring prior exposure to tensor analysis. General relativity is a fundamental cornerstone of physics that underlies several of the most exciting areas of current research, including relativistic astrophysics, cosmology, and the search for a quantum theory of gravity. The course briefly reviews special relativity, introduces basic aspects of differential geometry, including metrics, geodesics, and the Riemann tensor, describes black hole spacetimes and cosmological solutions, and concludes with the Einstein equation and its linearized gravitational wave solutions. At the level of Gravity: An Introduction to Einstein's General Relativity by Hartle.

ASTRO 7690 Computational Physics

Develops tools for using computers to model the physical world. Uses examples pulled broadly from core areas of physics: Mechanics, Electricity and Magnetism, Statistical Mechanics and Thermodynamics, and Quantum Mechanics. Focus is on algorithmic thinking, converting mathematical representations into practical algorithms, working with data, and drawing physical conclusions from numerical results. Model problems will involve numerical quadratures, ordinary and partial differential equations, numerical linear algebra, event based simulations, and Monte Carlo techniques. May include modern techniques, such as those drawn from machine learning and artificial intelligence. Instruction will largely be in Julia, with computer labs integrated into lectures. No prior experience with Julia is necessary, but students should have some experience with programming. Graduate versions, PHYS 7680 and ASTRO 7690, require an additional project which is not required in the undergraduate version, PHYS 4480.
