Near-UV and optical spectroscopic investigation of late-type stars from MIRA/Oliver Observing Station
Subhajeet Karmakar, Avrajit Bandyopadhyay, Wm. Bruce Weaver +4
Late-type stars are the most abundant in the galactic stellar population. These stars, with a similar internal structure to the Sun, are expected to have solar-like atmospheres. In…
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.…
