Magnetotails in the Solar System (Geophysical Monograph Series) - Peter Delamere, Caitr?ona Jackman, Andreas Keiling

Heliotail; short but fascinating chapter that I was looking forward to. It's short because experimental observations only started with the arrival of Voyager at the termination shock and the subsequent IBEX observations. These observations have radically altered our conception of the heliotail from being a gigantic equivalent of either Earth or Jupiter's magnetotail to   two short lobed structures termed Alfvén wings.
