Magnetic field, rotation, and binarity of the first magnetic B[e] star, IRAS 17449+2320
I. Bermejo Lozano, G. A. Wade, C. P. Folsom +1
IRAS 17449+2320 is the first identified magnetic B[e] star. It belongs to a subgroup of peculiar hot B-type stars, called FS~CMa stars. presenting the B[e] phenomenon, i.e., permit…
The rotational and magnetic properties of Polaris from long-term spectropolarimetric monitoring
James A. Barron, Gregg A. Wade, Colin P. Folsom
Polaris is a highly unusual Cepheid with observed properties that are difficult to reconcile with stellar evolutionary models. Since the initial detection of Polaris' magnetic fiel…
GMRT Survey of Radio Emission from Magnetic Massive Stars -- I: Emission from Single Stars at sub-GHz Frequencies
Ayan Biswas, Gregg A. Wade, Barnali Das +2
With the growing subset of magnetic massive stars, it is now possible to conduct a systematic survey of radio emission from magnetic hot stars to better understand the underlying e…
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), Le…
