An adiabatic approximation for grain alignment theory
W. G. Roberge
The alignment of interstellar dust grains is described by the joint distribution function for certain ``internal'' and ``external'' variables, where the former describe the orienta…
Interstellar Polarization in the Taurus Dark Clouds, Wavelength Dependent Position Angles and Cloud Structure Near TMC-1
D. W. Messinger, D. C. B. Whittet, W. G. Roberge
We use polarimetric observations of two stars (HD29647, HD283809) in the general direction of TMC-1 in the Taurus Dark Cloud to investigate grain properties and cloud structure in…
Cosmic rays and grain alignment
A. Lazarian, W. G. Roberge
The recent detection of interstellar polarization in the solid CO feature near 4.67 micron shows that CO-mantled grains can be aligned in cold molecular clouds. These observations…
Barnett Relaxation in Thermally-Rotating Grains
A. Lazarian, W. G. Roberge
We present an exact formulation of the physics of Barnett relaxation. Our formulation is based on a realistic kinetic model of the relaxation mechanism which includes the alignment…
