Discovery of a rapidly evolving global magnetic field in the M-dwarf YZ Cet and constraints on the magnetic field of its planet YZ Cet b
Ayan Biswas, Colin P. Folsom, James A. Barron +3
We present a spectropolarimetric study of the nearby M4.5V exoplanet host star YZ Cet, based on near-infrared observations obtained with the SpectroPolarimètre InfraRouge (SPIRou)…

A search for chemical stratification and magnetic fields in eight field blue horizontal-branch stars
Issouf Kafando, Gregg Wade, Alexandre David-Uraz +2
In this article, we present the results of an analysis of chemical abundances and a search for magnetic fields in eight field blue horizontal-branch (BHB) stars: BD\,+010…

Magnetic field monitoring of four massive A-F supergiants
Gregg Wade, Mary Oksala, Coralie Neiner +2
We report magnetic field measurements spanning about 15 years of four massive () supergiant stars: Per (HD\,20902, F5Iab), Lep (HD\,36673A, F0Ib), Leo (…
