Measuring and characterizing the line profile of HARPS with a laser frequency comb

Fei Zhao, G. Lo Curto, L. Pasquini +13

Aims. We study the 2D spectral line profile of HARPS (High Accuracy Radial Velocity Planet Searcher), measuring its variation with position across the detector and with changing li…

The solar gravitational redshift from HARPS-LFC Moon spectra. A test of the General Theory of Relativity

J. I. González Hernández, R. Rebolo, L. Pasquini +15

The General Theory of Relativity predicts the redshift of spectral lines in the solar photosphere, as a consequence of the gravitational potential of the Sun. This effect can be me…
