Alfvén waves are perturbations of the interplanetary magnetic field that transport energy. We use in situ measurements from the Parker Solar Probe and Solar Orbiter spacecraft to investigate a stream of solar wind as it traverses the inner heliosphere. The observations show heating and acceleration of the plasma between the outer edge of the corona and near the orbit of Venus, along with the presence of large-amplitude Alfvén waves. We calculate that the damping and mechanical work performed by the Alfvén waves are sufficient to power the heating and acceleration of the fast solar wind in the inner heliosphere. date: 2024-08-30 date_type: published publisher: American Association for the Advancement of Science (AAAS) official_url: http://dx.doi.org/10.1126/science.adk6953 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2310409 doi: 10.1126/science.adk6953 medium: Print-Electronic lyricists_name: Owen, Christopher lyricists_id: CJOWE13 actors_name: Owen, Christopher actors_id: CJOWE13 actors_role: owner full_text_status: public publication: Science volume: 385 number: 6712 pagerange: 962-966 event_location: United States citation: Rivera, Yeimy J; Badman, Samuel T; Stevens, Michael L; Verniero, Jaye L; Stawarz, Julia E; Shi, Chen; Raines, Jim M; ...
