Grain alignment induced by radiative torques: effects of internal relaxation of energy and complex radiation fields
Thiem Hoang, Alex Lazarian
Earlier studies of grain alignment dealt mostly with interstellar grains that have strong internal relaxation of energy which aligns grain axis of maximum moment of inertia with re…
Alignment of Dust with Magnetic Inclusions: Radiative Torques and Superparamagnetic Barnett and Nuclear Relaxation
A. Lazarian, T. Hoang
We consider grains with superparamagnetic inclusions and report two new condensed matter effects that can enhance the internal relaxation of the energy of a wobbling grain, namely,…
Radiative torques alignment in the presence of pinwheel torques
T. Hoang, A. Lazarian
We study the alignment of grains subject to both radiative torques and pinwheel torques while accounting for thermal flipping of grains. By pinwheel torques we refer to all systema…
The Efficiency of Grain Alignment in Dense Interstellar Clouds: A Reassessment of Constraints from Near Infrared Polarization
D. C. B. Whittet, J. H. Hough, A. Lazarian +1
A detailed study of interstellar polarization efficiency toward molecular clouds is used to attempt discrimination between grain alignment mechanisms in dense regions of the ISM. B…
Radiative torques: Analytical Model and Basic Properties
Alex Lazarian, Thiem Hoang
We attempt to get a physical insight into grain alignment processes by studying basic properties of radiative torques (RATs). For this purpose we consider a simple toy model of a h…
Subsonic Mechanical Alignment of Irregular Grains
Alex Lazarian, Thiem Hoang
We show that grains can be efficiently aligned by interacting with a subsonic gaseous flow. The alignment arises from grains having irregularities that scatter atoms with different…
Radiative torque alignment: Essential Physical Processes
Thiem Hoang, Alex Lazarian
We study the physical processes that affect the alignment of grains subject to radiative torques (RATs). To describe the action of RATs, we use the analytical model (AMO) of RATs i…
