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.…
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…
Near-Infrared atmospheric modelling of Jupiter's South Equatorial Belt (SEB) observed with AAT/IRIS2
Behrooz Karamiqucham, Jeremy A. Bailey, Lucyna Kedziora-Chudczer +1
Near-Infrared spectra of Jupiter's South Equatorial Belt (SEB) with AAT/IRIS2 in H and K bands at a resolving power of R~2400 have been obtained. By creating line-by-line radiative…
Polarization of hot Jupiter systems: a likely detection of stellar activity and a possible detection of planetary polarization
Jeremy Bailey, Kimberly Bott, Daniel V. Cotton +6
We present high-precision linear polarization observations of four bright hot Jupiter systems ( Boo, HD 179949, HD 189733 and 51 Peg) and use the data to search for polarized re…
