Line-by-line sensitivity to activity in M dwarf

Radial velocities (RVs) measured from high-resolution stellar spectra are routinely used to detect and characterise orbiting exoplanet companions. The different lines present in...从高分辨率恒星光谱中测得的视向速度（Radial Velocities，RVs），是当前探测与表征轨道运行系外行星伴体的常规手段。其中存在的不同谱线……
