About this award
This federal contract award, valued at $409,504.13, was granted by the National Aeronautics and Space Administration (NASA) to The Trustees of Princeton University's Office of Research and Project Administration. The contract supports research on the interactions between interstellar neutral atoms and the heliosphere, which provides insights into the properties of the very local interstellar medium. The work aims to improve the understanding of charge exchange processes that modify the flux of these interstellar atoms as they enter the heliosphere. This research will help interpret plasma properties in the heliosphere and its vicinity. The contract does not have a set-aside designation. Princeton University has a history of providing research services to various U.S. government agencies, including NASA, the Department of Defense, and the National Science Foundation, across a range of scientific domains.
Description
Science goals and objectives: interstellar neutral (ISN) atoms penetrating the heliosphere provide a remote diagnostic of the very local interstellar medium (vlism). Fluxes of ISN atoms are modified in the outer heliosheath by charge exchange (CX) collisions, which result in the production of secondary ISN atoms. A large part of our understanding of the vlism and the outer heliosphere comes from the attenuation of the ISN signal as observed at 1 AU to the source that lies outside the heliosphere. For this reason, details of the CX process are crucial for interpretating the plasma properties in the heliosphere and its vicinity. So far, analyses of the ISN atom observations from ibex-LO and ulysses/gas have neglected elastic scattering and assumed that particles in CX collisions conserve momenta of parent particles, i.e., that
