Reconnection in the ISM
Ethan T. Vishniac, A. Lazarian
We discuss the role of ambipolar diffusion for simple reconnection in a partially ionized gas, following the reconnection geometry of Parker and Sweet. When the recombination time…
On the efficiency of grain alignment in dark clouds
A. Lazarian, Alyssa A. Goodman, Philip C. Myers
A quantitative analysis of grain alignment in the filamentary dark cloud L1755 in Ophiuchus is presented. We show, that the observed decrease of the polarization to extinction rati…
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…
Paramagnetic alignment of thermally rotating dust
A. Lazarian
Paramagnetic alignment of thermally rotating oblate dust grains is studied analytically for finite ratios of grain to gas temperatures. For such ratios, the alignment of angular mo…
Gold alignment & internal dissipation
A. Lazarian
The measures of mechanical alignment were obtained for both prolate and oblate grains when their temperature is comparable with grain kinetic energy devided by k, the Boltzmann con…
