Grain alignment in dense interstellar environments : spectropolarimetry of the 4.67-m CO-ice feature in the field star Elias 16 (Taurus dark cloud)
(2008)
We present spectropolarimetry of the solid CO feature at 4.67 μm along the line of sight to Elias 16, a field star background to the Taurus dark cloud. A clear increase in polarization is observed across the feature with ...
Infrared Polarimetry of Interstellar Dust
(2005)
Grains in the diffuse interstellar medium, and in at least some parts of dense molecular clouds, are aligned with their short axis preferentially along the direction of the local magnetic field. At longer infrared wavelengths ...
Mid-infrared polarimetry and magnetic fields : an observing strategy
(2004)
Linear polarimetry in the mid-infrared can be used to obtain magnetic field directions in astronomical sources. However, since the polarization can arise from emission and/or absorption from aligned grains, care is needed ...

Spectropolarimetry of the 3-μm water-ice feature towards young stellar objects
(2002)
We present spectropolarimetry of the 3-μm water-ice feature towards five young stellar objects embedded in molecular clouds, including the Becklin–Neugebauer object, with wavelength range and spectral resolution much ...
Magnetic fields in discs : what can be learned from infrared and mm polarimetry ?
(2002)
Polarimetric imaging in the infrared and submm offers the possibility of identifying magnetic field configurations in astronomical objects. To test this conjecture a set of field geometries within internally heated discs ...
