Slow electron phase space holes: Magnetotail observations
2015 (English)In: Geophysical Research Letters, ISSN 0094-8276, Vol. 42, no 6, 1654-1661 p.Article in journal (Refereed) Published
We report multispacecraft observations of slow electrostatic solitary waves in the plasma sheet boundary layer. The electrostatic solitary waves are embedded in a region with field-aligned electron flows and are interpreted as electron phase space holes. We make unambiguous velocity and length estimates of the electron holes, v(EH)approximate to 500 km/s and l(||)approximate to 2-4(De), where l(||) is the parallel half width. We do not detect any magnetic signature of the holes. The electrostatic potentials of the holes are of the order e/k(B)T(e)approximate to 10%, indicating that they can affect electron motion and further couple the electron and ion dynamics.
