On rotation and expansion of spicules.
Abstract
Observed Hα profiles of spicules are compared with calculated profiles of rotating and expanding spicules. Of 66 observed spicules 14 profiles are in satisfactory agreement with profiles of rotating spicules and 8 profiles with those of expanding spicules. This suggests expansion and rotation in the corresponding spicules. There is neither expansion nor rotation in the other 44 spicules.
