A Decade of Solar High-Fidelity Spectroscopy and Precise Radial Velocities from HARPS-N
X. Dumusque, K. Al Moulla, M. Cretignier +53
We recently released 10 years of HARPS-N solar telescope and the goal of this manuscript is to present the different optimisations made to the data reduction, to describe data cura…
Using Doppler Imaging to model stellar activity and search for planets around Sun-like stars
Baptiste Klein, Suzanne Aigrain, Michael Cretignier +9
Doppler Imaging (DI) is a well-established technique to map a physical field at a stellar surface from a time series of high-resolution spectra. In this proof-of-concept study, we…
Measuring the Suns radial velocity variability due to supergranulation over a magnetic cycle
Niamh K. O'Sullivan, Suzanne Aigrain, Michael Cretignier +9
In recent years supergranulation has emerged as one of the biggest challenges for the detection of Earth-twins in radial velocity planet searches. We used eight years of Sun-as-a-s…
