Marvin K. Morgan II
I'm a Astronomer
About
Welcome to my academic webpage. My name is Marvin Morgan and I am a fifth year graduate student at the University of California, Santa Barbara pursuing a Ph.D. in Physics and Astrophysics. I work with Professor Brendan P. Bowler on using historical records of extrasolar planetary system architectures and orbits to understand how giant extrasolar planets form and evolve from both theoretical models and observational data. I utilize ground and space based observatories, such as the James Webb Space Telescope, Transiting Exoplanet Survey Satellite, Kepler space telescope, W. M. Keck Observatory in Hawaii, Hobby-Eberly Telescope in West Texas, and MINERVA-Australis in Australia to establish the relative importance of giant planet migration channels.
Prior to attending UCSB, I graduated with Distinction in Physics, a Bachelors of Arts in Physics & Astrophysics, and a Master of Science in Physics & Astronomy from the University of Pennsylvania. While at Penn, I worked with Professor Robyn Sanderson, Professor Konstantin Batygin (Caltech), and Professor Darryl Seligman (Michigan State University) on the dynamics and evoltuion of the giant planets in the early solar system. I then obtained a Master of Science in Astronomy & Astrophysics at the University of Texas at Austin working with Professor Bowler.
When I'm not solving fundamental problems in exoplanet astronomy, I enjoy working out and cooking. I was captain of the Men's Varsity Track and Field team at Penn where I was a two-ime Ivy League Champion and School record holder in the 60m Dash and a member of the Men's Varsity Track and Field team at Texas.

Research Interests
Early Solar System Evolution

The large-scale structure of the solar system has been shaped by a transient dynamical instability that may have been triggered by the interaction of the giant planets with a massive primordial disk of icy debris. We investigated the conditions under which this primordial disk could have coalesced into planets using analytic and numerical calculations. Our results favor a scenario wherein the dynamical instability of the outer solar system began immediately upon the dissipation of the gaseous nebula to avoid the overproduction of Earth-mass planets in the outer solar system.

Host Star Obliquities

Transiting giant planets provide a natural opportunity to examine stellar obliquities (spin-orbit orientations), which offer clues about the origin and dynamical histories of close-in planets. Hot Jupiters orbiting Sun-like stars show a tendency for obliquity alignment, suggesting that obliquities are rarely excited or that tidal realignment is common. However, the obliquity distribution is less clear for giant planets at wider separations where realignment mechanisms are not expected to operate.
