论文摘要
我们研究内部太阳系中共晶尘的动力学，即太阳辐射压力，Poynting-Robertson效应，太阳能风和行星际磁场在带电的谐振运动的位置，宽度和稳定性上的动力学，并稳定在1：1均匀的尘埃粒度以及平均运动式运动环境中。我们发现，通过分析和数值方法，在非重力效应的影响下，在库中心的位置和库宽度的$ L_4 $和$ L_5 $之间的偏差和不对称性。一旦我们考虑到太阳辐射压力，Poynting-Robertson效应和太阳风阻力，三角形拉格朗日点就变得不稳定。洛伦兹力可能会进一步破坏轨道的稳定，尤其是对于小灰尘颗粒。我们还对圆形，椭圆限制的三体模型和包括所有行星（所有行星）更完整的模型进行了比较。
We study the dynamics of co-orbital dust in the inner solar system, i.e. the role of the solar radiation pressure, Poynting-Robertson effect, solar wind, and the interplanetary magnetic field on the location, width and stability of resonant motion of charged, and micron sized dust grains situated in the 1:1 mean motion resonance with planet Venus. We find deviations and asymmetry between $L_4$ and $L_5$ in locations of libration centers and libration width under the influence of non-gravitational effects via both analytical and numerical methods. The triangular Lagrangian points become unstable once we take into consideration solar radiation pressure, the Poynting-Robertson effect and solar wind drag. The Lorentz force could further destabilize the orbits, especially for small dust particles. We also make a comparison between the circular, elliptic restricted three-body model and a more complete model including all planets.
