2019年IAO理论高年组第4题-彗星粒子
来自astro-init
英文原题
4. Comet particles. Particles of characteristic cometary matter of various sizes come off a comet. Estimate, the characteristic sizes D of the particles which are not ejected outside the Solar System due to the solar radiation pressure.
Note: You will get more points for the solution if you first derive the algebraic formula of the answer D=f(a,b,c,d,e...) and only then get the numerical answer by inserting the numerical data a, b, c, d, e... into this formula.

4. 彗星粒子。一些典型的彗星物质构成的粒子从彗星上脱落下来。估计,不被太阳的辐射压弹射出太阳系的粒子的典型直径。
注意:如果你可以推导出解析形式的方程如D=f(a,b,c,d,e...),然后将所需参数a, b, c, d, e...代入得到数值答案,你可以得到额外的分数。
