Comparative study of small-scale magnetic fields on Boo A using optical and near-infrared spectroscopy
A. Hahlin, O. Kochukhov, P. Chaturvedi +12
Magnetic field investigations of Sun-like stars, using Zeeman splitting of non-polarised spectra, in the optical and H-band have found significantly different magnetic field streng…

A conclusive non-detection of magnetic field in the Am star o Peg with high-precision near-infrared spectroscopy
O. Kochukhov, A. M. Amarsi, A. Lavail +10
The A-type metallic-line (Am) stars are typically considered to be non-magnetic or possessing very weak sub-G magnetic fields. This view has been repeatedly challenged in the liter…
