Separating planetary reflex Doppler shifts from stellar variability in the wavelength domain
A. Collier Cameron, E. B. Ford, S. Shahaf +28
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…

Multi-band high resolution spectroscopy rules out the hot Jupiter BD+20 1790b - First data from the GIARPS Commissioning
I. Carleo, S. Benatti, A. F. Lanza +51
Context. Stellar activity is currently challenging the detection of young planets via the radial velocity (RV) technique. Aims. We attempt to definitively discriminate the nature o…
