New Insights from Revisiting the Rotation Period of the Strongly Magnetic O Star, NGC 1624-2
S. Seadrow, V. Petit, G. A. Wade +5
NGC 1624-2 hosts the strongest surface magnetic field found on an O star thus far. When applied across several epochs of observations, the star's currently accepted rotation period…
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…
First Observation of the Complete Rotation Period of the Ultra-Slowly Rotating Magnetic O Star HD 54879
C. Erba, C. P. Folsom, A. David-Uraz +6
HD 54879 is the most recently discovered magnetic O-type star. Previous studies ruled out a rotation period shorter than 7 years, implying that HD 54879 is the second most slowly-r…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
X-Shooting ULLYSES: Massive stars at low metallicity. III. Terminal wind speeds of ULLYSES massive stars
C. Hawcroft, H. Sana, L. Mahy +26
The winds of massive stars have an impact on stellar evolution and on the surrounding medium. The maximum speed reached by these outflows, the terminal wind speed, is a global wind…
Spin-down and reduced mass loss in early-type stars with large-scale magnetic fields
Z. Keszthelyi, A. de Koter, Y. Götberg +12
Magnetism can greatly impact the evolution of stars. In some stars with OBA spectral types there is direct evidence via the Zeeman effect for stable, large-scale magnetospheres, wh…
