Epsilon Sagittarii: An Extreme Rapid Rotator with a Decretion Disk
Jeremy Bailey, Fiona Lewis, Ian D. Howarth +3
We report high-precision multi-wavelength linear-polarization observations of the bright B9 (or A0) star Sagittarii. The polarization shows the distinctive wavelength dependenc…
Polarimetric detection of nonradial oscillation modes in the beta Cephei star beta Crucis
Daniel V. Cotton, Derek L. Buzasi, Conny Aerts +11
Here we report the detection of polarization variations due to nonradial modes in the beta Cephei star beta Crucis. In so doing we confirm 40-year-old predictions of pulsation-indu…
A study of the F-giant star Scorpii A: a post-merger rapid rotator?
Fiona Lewis, Jeremy Bailey, Daniel V. Cotton +3
We report high-precision observations of the linear polarization of the F1III star Scorpii. The polarization has a wavelength dependence of the form expected for a rapid ro…
The rotation of alpha Oph investigated using polarimetry
Jeremy Bailey, Daniel V. Cotton, Ian D. Howarth +2
Recently we have demonstrated that high-precision polarization observations can detect the polarization resulting from the rotational distortion of a rapidly rotating B-type star.…
