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…
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…
Phase-locked polarization by photospheric reflection in the semidetached eclipsing binary Sco
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +1
We report the detection of phase-locked polarization in the bright (=2.98-3.24) semidetached eclipsing binary Sco (HD 151890). The phenomenon was observed in multiple ph…
Polarization measurements of the polluted white dwarf G29-38
Daniel V. Cotton, Jeremy Bailey, J. E. Pringle +3
We have made high precision polarimetric observations of the polluted white dwarf G29-38 with the HIgh Precision Polarimetric Instrument 2. The observations were made at two differ…
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.…
The polarization of the binary system Spica, and the reflection of light from stars
Jeremy Bailey, Daniel. V. Cotton, Lucyna Kedziora-Chudczer +2
Close binary systems often show linear polarization varying over the binary period, usually attributed to light scattered from electrons in circumstellar clouds. One of the brighte…
