Prof. Matthaeus helps explain characteristics of swirling solar wind

November 10, 2015 - Just a few hundred yards from the house where Italian astronomer Galileo Galilei (1564-1642) lived in Arcetri for the last nine years of his life, the University of Delaware's William Matthaeus is working to further the world's understanding of the heliosphere - the big bubble of magnetism that holds the solar system together - and especially its turbulent nature. Matthaeus, professor of physics and astronomy who specializes in heliospheric plasma physics and turbulence theory, is steering the Arcetri 2015 Workshop on Plasma Astrophysics this week. Last month he was co-author of a paper published in Astrophysical Journal that described new insights into the turbulence and temperatures of solar wind, which have presented difficult questions to astronomers and physicists for many years.
