Separating planetary reflex Doppler shifts from stellar variability in the wavelength domain

ABSTRACT Stellar magnetic activity produces time-varying distortions in the photospheric line profiles of solar-type stars. These lead to systematic errors in high-precision radial-velocity measurements, which limit efforts to discover and measure the masses of low-mass exoplanets with orbital perio...
