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…
Intermediate-Mass Mergers: A New Scenario for Several FS CMa Stars
Daniela Korcakova, Nela Dvorakova, Iris Bermejo Lozano +6
We summarise the properties and nature of a peculiar group of B-type stars called FS CMa stars. These stars show the B[e] phenomenon, i.e., their spectra exhibit both forbidden emi…
SpecpolFlow: a new software package for spectropolarimetry using Python
Colin P. Folsom, Christiana Erba, Veronique Petit +8
Spectropolarimetry, the observation of polarization and intensity as a function of wavelength, is a powerful tool in stellar astrophysics. It is particularly useful for characteriz…
