Effective & Ethical Mentorship in Physics and Astronomy through Grassroots Organizations
Natasha Latouf, Emma Schwartzman, Jeffrey McKaig +2
Effective and ethical mentorship practices are crucial to improving recruitment and retention especially for historically minoritized groups (HMGs). Spectrum is a diversity, inclus…
The alignment of interstellar dust grains: thermal flipping and the Davis-Greenstein mechanism
Joseph C. Weingartner, Erald Kolasi, Cameron Woods
Interstellar dust grains are non-spherical and, in some environments, partially aligned along the direction of the interstellar magnetic field. Numerous alignment theories have bee…
Barnett relaxation in non-symmetric grains
Erald Kolasi, Joseph C. Weingartner
Barnett relaxation, first described by Purcell in 1979, appears to play a major role in the alignment of grains with the interstellar magnetic field. In 1999, Lazarian and Draine p…
Alignment of interstellar grains by mechanical torques: suprathermally rotating Gaussian random spheres
Indrajit Das, Joseph C. Weingartner
Collisions of gas particles with a drifting grain give rise to a mechanical torque on the grain. Recent work by Lazarian & Hoang showed that mechanical torques might play a signifi…
Electric dipole moments and disalignment of interstellar dust grains
Margaret E. Jordan, Joseph C. Weingartner
The degree to which interstellar grains align with respect to the interstellar magnetic field depends on disaligning as well as aligning mechanisms. For decades, it was assumed tha…
Thermal Flipping of Interstellar Grains
Joseph C. Weingartner
In interstellar dust grains, internal processes dissipate rotational kinetic energy. The dissipation is accompanied by thermal fluctuations, which transfer energy from the vibratio…
