  • article-nadc研究人员发现早型M型恒星是寻找系外行星的绝佳目标 ，发现早型M型恒星（质量大于0.35倍太阳质量）拥有行星的概率更大，而质量小于0.35倍太阳质量的M型恒星虽然拥有行星的概率较小，但也可以拥有类木星行星。已有的研究结果显示，M型矮星几乎占所有恒星总数的3/4，其中约1/7的M型矮星拥有宜居带行星，因此M型矮星应该拥有绝大多数宜居行星。图1：M型恒星的行星系统示意图（Danielle Futselaar/METI） M型恒星为何具有如此多的行星？小质量的M型矮星周围为何不容易形成大质量的类木星行星？ ...为了回答上面两个问题，李广伟等人利用LAMOST光谱数据，结合Gaia、2MASS和WISE测光数据对M型年轻恒星的星周盘进行了系统研究，他们发现这些M型年轻恒星的完整盘（含有丰富气体和尘埃的原初星周盘 ...因此，研究团队认为：质量大于0.35倍太阳的M型恒星更容易拥有行星；质量小于0.35倍太阳的M型恒星也可以拥有类木星行星，但数量很少；由于缺少物质，小质量的恒星无法成长为质量更大的恒星。
