The Numbers and Motions of Solar Spicules.
Abstract
In this paper we interpret spicule motions in terms of two spicule models, one with constant velocity and one decelerating in the solar gravitational field. The available statistics slightly favor the gravitational model but do not indicate clearly which model is preferred. We estimate the total number of spicules on the sun by fitting the two spicule models to the observed distribution of spicules with height. This leads to total spicule numbers of 1.4 X 10 to 1.3 X 1O for the two models.
