A fast method for deriving relative small-scale magnetic field variations from high-resolution spectroscopy
Paul I. Cristofari, Steven H. Saar, Aline A. Vidotto +1
Observational constraints on stellar magnetic fields are essential to both stellar and planetary physics. Recent studies revealed the diversity and evolution of large-scale magneti…

Stellar Surface Magneto-Convection as a Source of Astrophysical Noise II. Center-to-Limb Parameterisation of Absorption Line Profiles and Comparison to Observations
H. M. Cegla, C. A. Watson, S. Shelyag +6
Manifestations of stellar activity (such as star-spots, plage/faculae, and convective flows) are well known to induce spectroscopic signals often referred to as astrophysical noise…
