Embry-Riddle Student's Study of Hurricanes in Space Wins National First Prize
Daytona Beach, FL, May 8, 2012
Emily Hyatt, an engineering physics undergraduate student at Embry-Riddle Aeronautical University, has won first prize in magnetospheric physics in a student research contest sponsored by the National Science Foundation (NSF) and the Community Coordinate Modeling Center, which conducts research in space science and develops new space weather models. Her competitors included Ph.D. students from around the country.
Hyatt used simulations to calculate the location, size and travel time of the Kelvin-Helmholtz Instability (KHI), huge magnetic hurricanes in space that can break through Earth’s magnetic barrier and spill solar wind plasma into our planetary “backyard.” They can cause auroral ionospheric disturbances similar to the Northern Lights. The phenomenon may also explain the loss of atmosphere on Mars.
While these hurricanes are two to three times larger than Earth, they are dwarfed by the environment where they occur. Hyatt’s work is important because these magnetic hurricanes are rarely observed in the magnetosphere due to the enormous size of space and the small number of spacecraft.
She did it by analyzing all published cases of KHI, as well as several new cases identified by Thomas Moore, an Embry-Riddle graduate student who received honorable mention in the magnetospheric physics category.
“Emily’s work can be used to ‘reverse engineer’ the detection of the magnetospheric KHI by observing directly its effect on the ionosphere,” said Katariina Nykyri, associate professor of physics and Hyatt’s faculty advisor. “Emily’s research paper is the first step in this process, as we now know what kind of signatures we can expect to see and where, and how long it takes along the magnetic field lines for the magnetospheric disturbance to travel to the ionosphere.”
The research by Hyatt was funded by a prestigious NSF Career Award granted to Nykyri in 2009 for her research on space hurricanes.
Hyatt will present her work at the National Science Foundation’s Geospace Environment Modeling workshop June 17-22. An Army ROTC cadet, she will receive her bachelor’s degree on May 13 and then will pursue a master’s degree in engineering physics at Embry-Riddle. It will be funded by Sandia National Laboratories.
“Emily’s work is consistent with Embry-Riddle’s IGNITE! program, which encourages students to get involved in research,” Nykyri said. Embry-Riddle is unique among U.S. universities in the extent that its undergraduate students take part in applied research.
Embry-Riddle Aeronautical University, the world's largest, fully accredited university specializing in aviation and aerospace, is a nonprofit, independent institution offering more than 40 baccalaureate, master's and Ph.D. degree programs in its colleges of Arts and Sciences, Aviation, Business and Engineering. Embry-Riddle educates students at residential campuses in Daytona Beach, Fla., and Prescott, Ariz., and through the Worldwide Campus with more than 150 locations in the United States, Europe, Asia, and the Middle East. The university is a major research center, seeking solutions to real-world problems in partnership with the aerospace industry, other universities and government agencies.
