Gl 49 radial velocities and activity indicators

Small planets around low-mass stars often show orbital periods in a range that corresponds to the temperate zones of their host stars which are therefore of prime interest for...低质量恒星周围的小型行星，其轨道周期往往处于与宿主恒星宜居带（temperate zones）相对应的区间内，因此该类行星对于……具有核心研究价值。
