Astrobiological signatures: prospects for the detection of non-terrestrial biological material
(2007)
The possibilities for detecting non-terrestrial biological material are briefly reviewed in light of the flurry of extrasolar planet detections over the last ten years and the forthcoming space missions designed to search ...
Alignment of atmospheric mineral dust due to electric field
(2007)
Optical polarimetry observations on La Palma, Canary Islands, during a Saharan dust episode show dichroic extinction indicating the presence of vertically aligned particles in the atmosphere. Modelling of the extinction ...
Low Polarization Standards
(Astronomical Society of the Pacific, 2007)
There is renewed interest in high sensitivity polarimetry as a means of observing the polarization signal of extra-solar planets. We describe the measurement of low polarized standards at fractional polarizations of parts ...
