本文将列出，调查，并评估各种自旋机制的宇宙尘埃粒子已在文献中提出。这项评估将集中于宇宙尘埃粒子碎裂（旋转爆发）的可能性。颗粒破碎的重要性表现在粉尘颗粒尺寸分布将发生变化。更重要的是，行星际尘埃粒子的反复碎裂将产生一些观测到的“β流星体”。其中一些粒子被太阳辐射压力赶出太阳系，进入星际空间。如果这种质量损失机制发生在恒星系统中，那么它就会成为星际尘埃的来源。本文还讨论了大规模的旋转爆发的环日尘埃粒子发生在F日冕区域的可能性。这种F日冕尘埃的旋转爆发可能是由于经典的“帕达克效应”，沿着作者提出的类似的旋转机制，并由日冕物质抛射引起的。
This paper will list, investigate, and evaluate the various spin mechanisms for cosmic dust particles that have been suggested in the literature. This evaluation will concentrate on the possibility of particle fragmentation (rotational bursting) of cosmic dust. The importance of particle fragmentation is manifested by the fact that dust particle size distribution will be changed. More importantly, repeated fragmentation of interplanetary dust particles will give rise to some of the observed “β meteoroids.” Some of these particles are driven out of the solar system and into interstellar space by solar radiation pressure. If this mass loss mechanism is taking place in stellar systems, then it becomes a source for interstellar dust. This paper also addresses the possibility that massive rotational bursting by circumsolar dust particles is taking place in the F corona region. This rotational bursting of F coronal dust could be taking place because of the classical “Paddack effect,” along with a similar spin mechanism suggested by the author, and caused by coronal mass ejections.
