Fedorov, A.; Barabash, S.; Lundin, R. +3 more

Data from the neutral particle imager (NPI) on Venus Express reveals the presence of a persistent +Y (Venus Solar-Oriented) flow of Energetic Neutral Atoms (ENAs) in the Venus polar thermosphere. The overall flow morphology and altitude distribution of ENAs, solar wind H⁺ (SWH⁺), and ionospheric O⁺ imply that SWH
