About this person
In 1958, he proposed the existence of the solar wind and predicted that the magnetic field in the outer Solar System would be in the shape of a Parker spiral - predictions initially rejected by reviewers and scientific community, but quickly confirmed by the Mariner 2 spacecraft in 1962. Multiple phenomena in solar and plasma physics bear his name, including the Parker instability, Parker equation, Sweet-Parker model of magnetic reconnection, Parker limit on magnetic monopoles, and Parker theorem. In 1988, he proposed that nanoflares could explain the coronal heating problem, a theory that remains a leading candidate.
