Cross Section Alignment of Oblate Grains

  title={Cross Section Alignment of Oblate Grains},
  author={Alex Lazarian and Michael Efroimsky},
  journal={The Astrophysical Journal},
This paper provides a quantitative account of a recently introduced mechanism of mechanical alignment of suprathermally rotating grains. These rapidly rotating grains are essentially not susceptible to random torques arising from gas-grain collisions, as the timescales for such torques to have significant effect are orders of magnitude greater than the mean time between crossovers. Such grains can be aligned by gaseous torques during the short periods of crossovers and/or due to the difference…

Mechanical Alignment of Prolate Cosmic-Dust Grains: Cross Section Alignment

This paper deals with the quantitative analysis of a recently introduced mechanism of mechanical alignment of suprathermally rotating cosmic-dust grains. These grains, whose rapid rotation is mostly

Disorientation of Suprathermally Rotating Grains and the Grain Alignment Problem

We discuss the dynamics of dust grains subjected to torques arising from H2 formation. In particular, we discuss grain dynamics when a grain spins down and goes through a “crossover” event. As first

Gold Alignment and Internal Dissipation

The measures of mechanical alignment are obtained for both prolate and oblate grains whose temperatures are comparable to the grain kinetic energy divided by k, the Boltzmann constant. For such

Mechanical Alignment of Suprathermal Paramagnetic Cosmic-Dust Granules: The Cross Section Mechanism

We develop a comprehensive quantitative description of the cross section mechanism discovered by Lazarian. This is one of the processes that determine grain orientation in clouds of suprathermal

Alignment of Irregular Grains by Mechanical Torques

We study the alignment of irregular dust grains by mechanical torques due to the drift of grains through the ambient gas. We first calculate mechanical alignment torques (MATs) resulting from

On the Efficiency of Grain Alignment in Dark Clouds

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 ratio for the inner

Grain Alignment in the Circumstellar Shell of IRC+10° 216

Dust-induced polarization in the interstellar medium (ISM) is due to asymmetric grains aligned with an external reference direction, usually the magnetic field. For both the leading alignment

Interstellar Dust Grain Alignment

Interstellar polarization at optical-to-infrared wavelengths is known to arise from asymmetric dust grains aligned with the magnetic field. This effect provides a potentially powerful probe of


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 systematic torques that

Grain Alignment by Radiation in Dark Clouds and Cores

We study alignment of grains by radiative torques. We found a steep rise in radiative torque efficiency as grain size increases. This allows the larger grains that are known to exist within molecular
