Stellar surface information from the Ca II H&K lines -- II. Defining better activity proxies
M. Cretignier, N. C. Hara, A. G. M. Pietrow +6
In our former paper I, we showed on the Sun that different active regions possess unique intensity profiles on the Ca II H & K lines. We now extend the analysis by showing how thos…

Measuring precise radial velocities on individual spectral lines. III. Dependence of stellar activity signal on line formation temperature
K. Al Moulla, X. Dumusque, M. Cretignier +2
Context. To enable radial velocity (RV) precision on the order of ~0.1 m/s required for the detection of Earth-like exoplanets orbiting solar-type stars, the main obstacle lies in…
