Research and Teaching Interests

We are working with the Science Team for the TWINS satellite NASA mission of opportunity. The two spacecraft are in Molniya orbits with perigee altitudes of ~1000 km and apogees in the northern hemisphere at ~7.2 RE. The spacecraft are 3-axis stabilized and provide approximately nadir pointing of the TWINS instruments. The instruments image energetic neutral atoms coming from the Earth's inner magnetosphere. The neutrals are created by charge exchange between energetic ions and cold neutral hydrogen. It is the ions that are of interest. The Auburn group specializes in extracting information about the ions trapped in the Earth's ring current from the neutral atom images. This technique is giving scientists the opportunity to see the invisible. We are also working with other AU scientists and collaborators at the Goddard Space Flight Center in Greenbelt, MD to develop simulation codes to study the injection of ions into the Earth's ring current from the Earth's magnetotail. The code will be the first 3D hybrid code combined with a comprehensive ring current model and will allow scientists to understand the dynamic behavior observed by satellites in the Earth's magnetosphere.
