Journal ArticleDOI
Long- and short-term variability in O-star winds. I. Time series of UV spectra for 10 bright O stars.
TL;DR: In this paper, an atlas of time series of ultraviolet spectra is presented for 10 bright O stars, with the spectra obtained with the International Ultraviolet Explorer during seven observing campaigns lasting several days over a period of 6 years.
Journal ArticleDOI
Discovery of a magnetic field in the Slowly Pulsating B star ζ Cassiopeiae
C. Neiner,C. Neiner,C. Neiner,V. C. Geers,H.F. Henrichs,M. Floquet,Y. Fremat,A. M. Hubert,O. Preuss,Klaas Wiersema +9 more
TL;DR: In this article, the authors detect a magnetic field in an early B-type pulsating star and classify it as a slowly pulsating B (SPB) star with an unambiguous rotation period of 5.37 days, corresponding to the 5.37045 day period as derived from stellar wind variations observed in the ultraviolet.
Journal ArticleDOI
Rotation, pulsations and magnetic field in V 2052 Ophiuchi: A new He-strong star
C. Neiner,C. Neiner,C. Neiner,H.F. Henrichs,M. Floquet,Y. Fremat,O. Preuss,A. M. Hubert,V. C. Geers,A. H. Tijani,J.S. Nichols,Slobodan Jankov +11 more
TL;DR: In this paper, the magnetic properties of the star V 2052 Oph have been studied in the ultraviolet wavelength region with the IUE satellite, revealing periodic variations in the equivalent widths (EW) of the resonance lines of wind sensitive ions with a period of 3.638833 d, which is identified as the rotational period.
Journal ArticleDOI

TL;DR: In this paper, 40 high-resolution circular spectropolarimetric measurements of 12 slowly pulsating B (SPB) stars, eight β Cephei stars and two Be stars were obtained with the Echelle Spectropolimetric Device for the Observation of Stars at CFHT (ESPaDOnS) and Narval spectropolimeters.
Journal ArticleDOI
Line-profile variations due to adiabatic non-radial pulsations in rotating stars. I. Observable characteristics of spheroidal modes
TL;DR: In this paper, the surface-velocity field of a rotating, adiabatically pulsating star, which accounts for the effects of the Coriolis force, is considered.
