太阳质量突变对类地行星轨道的影响

Influence of Abrupt Change of Solar Mass on the Earth-like Planetary Orbit

假设太阳演化为白矮星的终止质量范围是0．4551～0．5813M0，太阳抛射壳层的速率远大于类地行星的公转速率，认为太阳的质量变化是瞬间的。在太阳抛射壳层的模型下，类地行星获得的径向速率的数值与其公转速率的数值在同一量级，类地行星的轨道偏心率的变化范围是1．7949～0．7240。

Assuming that the terminated mass is confined within the range 0.4551 - 0.5813M when sun is going to evolve into White Dwarf, the velocity sun ejecting the shell is much greater than the revolving velocity of earth-like planet, therefore we think that the solar mass change is instantaneous. Under the model of sun ejecting the shell, the radial velocity of earth-like planot has the same order of magnitude as its revolving velocity, the orbital eccentricity of earth-like planet varies with the range 1.7949- 0.7240.
