Analytical and numerical modelling of magnetic flux rope structures in the heliosphere

Organization National Aeronautics and Space Administration (NASA) Reference Code 0251-NPP-NOV26-GSFC-HelioSci Application Deadline 11/1/2026 6:00:59 PM Eastern Time Zone Description The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one‑to‑three‑year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology. This project will be focused on the development of analytical and numerical modeling of magnetic flux rope structures in the heliosphere. This includes (1) axial or cross‑sectional deformations due to self‑interaction or external factors such as the coronal magnetic field or variations in the solar wind, (2) structural time evolution such as expansion or the evolution of magnetic twist, (3) stability constraints or conditions, (4) model configuration for comparison to real‑world in‑situ magnetic field measurements. The theoretical approaches that are developed within this program can be validated close to the Sun or near to Earth by using in‑situ or remote imaging data from currently operating missions such as Parker Solar Probe or STEREO.
