'''比邻星(Proxima Centaur)的行星'''<br />
<br />
一个天文学小组最近观测到比邻星的视向速度展现出周期性摆动，这意味着一颗行星在绕其转动。表9为在某轮观测中得到的视向速度（单位为m/s）与从观测开始的第几天（单位为days）的对应关系。比邻星的质量、半径和光度分别为太阳的0.12、0.14和1.5×10<sup>-3</sup>倍。假设该行星的轨道为圆形且轨道平面沿我们的视线方向。<br />
<br />
9.1 在绘图纸上画出比邻星的视向速度与时间的关系图。<br />
<br />
9.2 找出该行星的轨道周期以及比邻星视向速度的最大值。<br />
<br />
9.3 求出该行星的轨道半径，单位为au。<br />
<br />
9.4 算出该行星的质量，单位为$$M\oplus $$(地球质量)。<br />
<br />
9.5 （仅高年组）该行星的气候会如何？一颗光度为L，表面温度为T<sub>S</sub>的恒星，其宜居带的内边缘和外边缘到恒星的距离（分别为d<sub>1</sub>和d<sub>0</sub>）由下式给出：<br />
<br />
$$d_{1}=\sqrt{\frac{L/L\bigodot }{S_{1}(T_{S})}}au$$和$$d_{0}=\sqrt{\frac{L/L\bigodot }{S_{0}(T_{S})}}au$$<br />
<br />
式中$$L\bigodot $$为太阳的光度，S<sub>1</sub>(T<sub>S</sub>)和S<sub>0</sub>(T<sub>S</sub>)为在图9中取决于T<sub>S</sub>的参数，图9中横坐标单位为10<sup>3</sup>K。计算该行星是否位于比邻星的宜居带中，并写下最终结论Yes或No。<br />
<br />
