Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14
Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bot…
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…
Multi-wavelength aperture polarimetry of debris disc host stars
Jonathan P. Marshall, Daniel V. Cotton, Kimberly Bott +3
Debris discs around main sequence stars have been extensively characterised from infrared to millimetre wavelengths through imaging, spectroscopic, and total intensity (scattered l…
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…
PICSARR: high-precision polarimetry using CMOS image sensors
Jeremy Bailey, Daniel V. Cotton, Ain De Horta +2
We have built and tested a compact, low-cost, but very-high-performance astronomical polarimeter based on a continuously rotating half-wave plate and a high-speed imaging detector.…
