A scaling relationship for non-thermal radio emission from ordered magnetospheres - II. Investigating the efficiency of relativistic electron production in magnetospheres of BA-type stars

P. Leto, S. Owocki, C. Trigilio +19

Magnetic BA stars host dipole-like magnetospheres. When detected as radio sources, their luminosities correlate with the magnetic field and rotation. Rotation is crucial because th…

Discovery of the binary nature of the magnetospheric B-type star Oph A

M. E. Shultz, I. Berry, D. Bohlender +11

The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…

X-ray and radio data obtained by XMM-Newton and VLA constrain the stellar wind of the magnetic quasi-Wolf-Rayet star in HD45166

P. Leto, L. M. Oskinova, T. Shenar +9

Recently, a powerful magnetic field was discovered in the hot helium star classified as a quasi-Wolf-Rayet star of ~2Msun, member of the HD45166 system. Upon its explosion as a cor…

Horizontal flows in the atmospheres of chemically peculiar stars

A. ud-Doula, J. Krticka, B. Kubátová

Context. Classical chemically peculiar stars exhibit atmospheres that are often structured by the effects of atomic diffusion. As a result of these elemental diffusion and horizont…

X-Shooting ULLYSES: Massive Stars at Low Metallicity

Jorick S. Vink, Paul Crowther, Alex Fullerton +20

The Hubble Space Telescope has devoted 500 orbits to observing 250 massive stars with low metallicity in the ultraviolet (UV) range within the framework of the ULLYSES program. The…

Investigating the origin of cyclical wind variability in hot, massive stars - I. On the dipolar magnetic field hypothesis

A. David-Uraz, G. A. Wade, V. Petit +9

OB stars exhibit various types of spectral variability associated with wind structures, including the apparently ubiquitous discrete absorption components (DACs). These are propose…

Phase-resolved ultraviolet spectroscopy of the magnetic Of?p star HD 191612

W. L. F. Marcolino, J. -C. Bouret, J. O. Sundqvist +5

We present for the first time phase-resolved UV spectroscopy of an Of?p star, namely, HD 191612. The observations were acquired with the Space Telescope Imaging Spectrograph (STIS)…
