Rotational modulation in TESS B stars
L. A. Balona, G. Handler, S. Chowdhury +6
Light curves and periodograms of 160 B stars observed by the TESS space mission and 29 main-sequence B stars from Kepler and K2 were used to classify the variability type. There ar…
The effects of surface fossil magnetic fields on massive star evolution: I. Magnetic field evolution, mass-loss quenching and magnetic braking
Z. Keszthelyi, G. Meynet, C. Georgy +3
Surface magnetic fields have a strong impact on stellar mass loss and rotation and, as a consequence, on the evolution of massive stars. In this work we study the influence of an e…
Diverse Variability of O and B Stars Revealed from 2-minute Cadence Light Curves in Sectors 1 and 2 of the TESS Mission: Selection of an Asteroseismic Sample
May G. Pedersen, Sowgata Chowdhury, Cole Johnston +18
Uncertainties in stellar structure and evolution theory are largest for stars undergoing core convection on the main sequence. A powerful way to calibrate the free parameters used…
A JVLA survey of the high frequency radio emission of the massive magnetic B- and O-type stars
Sushma Kurapati, Poonam Chandra, Gregg Wade +10
We conducted a survey of seven magnetic O and eleven B-type stars with masses above using the Very Large Array in the 1cm, 3cm and 13cm bands. The survey resulted in a…
Understanding the photometric variability of ζ Ori Aa
B. Buysschaert, C. Neiner, T. Ramiaramanantsoa +3
We studied the variability of the magnetic O-type supergiant Ori Aa using multi-colour BRITE photometry. We confirmed the known rotation frequency …
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…
