THE MATERIAL MOTION IN A “POST”-FLARE LOOP PROMINENCE

【摘要】 <正> The velocity fields of a "post" - flare loop prominence taken in different times by thespectra- spectroheliograph are measured by the 3CS densitometer. According to the fundamentalfeatures of the observed velocity fields, we consider that the plasma matter within the loopprominence, which is formed by the magnetic reconnection after flares, would flow down fromthe top of loops along the helical magnetic lines under the action of the gravity of the Sun andthe magnetic stress in the loop prominence. The theoretical distributive chart of the velocityfields of the loop prominence is basically in accordance with the observations.更多还原
