Current Sheets Observed by ACE and Ulyssess at Different Heliospheric Distances
Abstract
Current sheets are common structures in the solar wind. They may be the boundaries of flux tubes that originated from the surface structure of the Sun. Using an automatic searching code, the boundary of those flux tubes, i.e. the current sheets, are identified. Through the observations made by the ACE and Ulyssess spacecraft at the different heliospheric distance, the variation of the size and occurrences of those current sheets related to the heliospheric distance are investigated. Two kinds of current sheet populations are distinguished. The implication of our results on the solar wind MHD turbulence, in particular, the intermittency will be discussed.
