Al Moulla K. | Dumusque X.... - 《Astronomy and astrophysics》 - 2024,683 - 共15页 - 被引量：2

摘要：Context. Radial velocities (RVs) of stars | contain both the Doppler reflex motion of potential | planetary companions and the drowning and sometimes | imitating effect of stellar activity. To separate the two | , previous efforts have sought proxies that only trace the
