论文摘要
Burns等人。 （1979）使用参数β来描述太阳系中小粒子经历的辐射压力与重力的比率。这些颗粒体验的核心潜力有效地减少了（1-β），从而降低了逃逸速度。 Burns等人。 （1979年）还为β的值提供了一个简单的表达，在该值中，从彗星弹出的颗粒遵循抛物线轨道，从而离开太阳系。本文对此进行了扩展，以计算关键的Beta值，以考虑射血速度。我们首先得出一个表达式，该表达式是从所有粒径有效的彗星中弹出颗粒的速度。然后，我们计算理想化和真实材料的Beta值，以确定流星流丢失哪些颗粒。我们对彗星射流前的前射，尾随和遵循父母彗星的核进行了这些计算，用于10个主要的流星阵雨。这些值结合了从太阳系中弹出流星的质量制度，因此不能导致流星阵雨。
Burns et al. (1979) use the parameter beta to describe the ratio of radiation pressure to gravity experienced by a small particle in the solar system. The central potential that these particles experience is effectively reduced by a factor of (1 - beta), lowering the escape velocity. Burns et al. (1979) also provide a simple expression for the value of beta at which particles ejected from a comet follow parabolic orbits and thus leave the solar system; this paper expands on this to calculate critical beta values that take ejection velocity into account. We first derive an expression for the speed at which particles are ejected from a comet that is valid at all particle sizes. We then calculate beta values for both idealized and real materials to determine which particles will be lost from meteor streams. We perform these calculations for cometary ejecta leading, trailing, and following the parent comet's nucleus for 10 major meteor showers. These values bound mass regimes within which meteoroids are ejected from the solar system and therefore cannot contribute to meteor showers.
