    A new method for instrumental profile reconstruction of high-resolution spectrographs
    GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then...

    A new method of measuring centre-of-mass velocities of radially pulsating stars from high-resolution spectroscopy
    We present a radial velocity analysis of 20 solar neighbourhood RR Lyrae and three Population II Cepheid variables. We obtained high-resolution, moderate-to...

    A new procedure for defining a homogenous line-list for solar-type stars
    Context. The homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it...
