Grain Dynamics In Photodissociation Regions (2008)
J.C. Weingartner, B. T. Draine
We discuss the forces on grains exposed to anisotropic radiation fields, including the usual "radiation pressure " force and also recoil forces due to photoemitted electrons, photodesorbed...
Photoelectric Emission from Interstellar Dust: Grain Recoil Forces and Gas Heating (2007)
Joseph C. Weingartner, B.T. Draine
Interstellar grains exposed to anisotropic radiation are subjected to forces due to recoil from escaping photoelectrons. This "photoelectric" force, which depends on grain charge and...
Optical and Magnetic Properties of Dust Grains (2007)
Draine Princeton, B. T. Draine
. The optical and magnetic properties of dust grains are reviewed, as they relate to the problem of interstellar grain alignment. Grain geometry plays an important role in determining the optical...
Disorientation of Suprathermally Rotating Grains and the Grain Alignment Problem (2007)
Lazarian Draine, A. Lazarian, B. T. Draine
We discuss the dynamics of dust grains subjected to uncompensated torques arising from H 2 formation. In particular, we discuss grain dynamics when a grain spins down and goes through a...
Thermal Flipping and Thermal Trapping -- New Elements in Dust Grain Dynamics (2007)
Lazarian Draine, A. Lazarian, B. T. Draine
Since the classical work by Purcell (1979) it has been generally accepted that most interstellar grains rotate suprathermally. Suprathermally rotating grains would be nearly perfectly aligned with...
Grain Destruction In Interstellar Shock Waves (2007)
Draine Princeton, B. T. Draine
. Interstellar shock waves can erode and destroy grains present in the shocked gas, primarily as the result of sputtering and grain-grain collisions. Uncertainties in current estimates of sputtering...
The Calibration of Mid-Infrared Star Formation Rate Indicators (2007)
