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…
Rapid polarization variations in the O4 supergiant Puppis
Jeremy Bailey, Ian D. Howarth, Daniel V. Cotton +5
We present time-series linear-polarization observations of the bright O4 supergiant Puppis. The star is found to show polarization variation on timescales of around an hour and…
Discovery of Dipolar Chromospheres in Two White Dwarfs
J. Farihi, J. J. Hermes, S. P. Littlefair +3
This paper reports the ULTRACAM discovery of dipolar surface spots in two cool magnetic white dwarfs with Balmer emission lines, while a third system exhibits a single spot, simila…
A study of the rapid rotator Aql: differential surface rotation?
Ian D. Howarth, Jeremy Bailey, Daniel V. Cotton +1
We report new, extremely precise, photopolarimetry of the rapidly-rotating A0 main-sequence star Aql, covering the wavelength range 400--900nm, which reveals a rotational…
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…
Properties of the Be-type stars in 30 Doradus
P. L. Dufton, D. J. Lennon, J. I. Villasenor +5
The evolutionary status of Be-type stars remains unclear, with both single-star and binary pathways having been proposed. Here, VFTS spectroscopy of 73 Be-type stars, in the spectr…
