Welcome! to my webpage, hosted by the Department of Physics & Astronomy at the University of Utah. I am a Professor, working in theoretical and computational astrophysics, with focus on planet formation, galactic dynamics, as well as some relativistic astrophysics. Here you will find information about my research, recent courses, and other things that I do at The U.

 

Research

   Highlights and animations


 
     Origin of Pluto's moons. Our favorite binary planet, Pluto-Charon, has four moons -- Styx, Nix, Kerberos, and Hydra -- packed together on nearly perfect, "almost circular" orbits. Scott Kenyon and I have worked to understand how they formed. Please see our latest manuscript about Pluto-Charon, and this animated "drive-thru" of the PC system.
       Black holes and hypervelocity stars! Warren Brown, Margaret Geller, Scott Kenyon, and I study the origin of hypervelocity stars, which travel so fast that they are escaping our Galaxy. . Some may have started out as members of binary stars in the Galactic Center, and got flung out when they strayed too close to the Galaxy's supermassive black hole. What happens to the binary partner? Here's one idea....
     Flyby! The Sun might have captured planets from a passing star. Animations that Scott Kenyon and I made (like THIS ONE!) show how this could happen.
