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…
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…
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…
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…
No evidence of a sudden change of spectral appearance or magnetic field strength of the O9.7V star HD 54879
G. A. Wade, S. Bagnulo, Z. Keszthelyi +8
It was recently claimed that the magnetic O-type star HD 54879 exhibits important radial velocity variability indicative of its presence in a spectroscopic binary. More remarkably,…
Surface magnetism of cool stars
O. Kochukhov, P. Petit, K. G. Strassmeier +10
Magnetic fields are essential ingredients of many physical processes in the interiors and envelopes of cool stars. Yet their direct detection and characterisation is notoriously di…
Chemical peculiarities in magnetic and non-magnetic pre-main sequence A and B stars
C. P. Folsom, S. Bagnulo, G. A. Wade +2
In A- and late B-type stars, strong magnetic fields are always associated with Ap and Bp chemical peculiarities. However, it is not clear at what point in a star's evolution those…
A detailed spectroscopic analysis of the open cluster NGC 5460
L. Fossati, C. P. Folsom, S. Bagnulo +5
Within the context of a large project aimed at studying early F-, A- and late B-type stars we present the abundance analysis of the photospheres of 21 members of the open cluster N…
How non-magnetic are "non-magnetic" Herbig Ae/Be stars?
G. A. Wade, E. Alecian, C. Catala +9
Our recent discovery of magnetic fields in a small number of Herbig Ae/Be stars has required that we survey a much larger sample of stars. From our FORS1 and ESPaDOnS surveys, we h…
Magnetic, Chemical and Rotational Properties of the Herbig Ae/Be Binary System HD 72106
C. P. Folsom, G. A. Wade, O. Kochukhov +5
Recently, strong, globally-ordered magnetic fields have been detected in some Herbig Ae and Be (HAeBe) stars, suggesting a possible evolutionary connection to main sequence magneti…
