On the Orientation of Dust Grains in Interstellar Space [PDF]

, 1962
The observed polarization of starlight is regarded as being due to absorption by interstellar dust. A mechanism for alignment of the dust grains, due to Davis and Greenstein, is analyzed. A dissipative torque, due to paramagnetic relaxation in the grains,

Monitoring of the Interstellar Dust Stream in the Inner Solar System Using Data of Different Spacecraft [PDF]

, 2004
Interstellar dust plays a key role in many astrophysical processes. However, until recently, astronomers could infer some properties of interstellar dust only through observations of starlight extinction and infrared emission.

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2

The Astrophysical Journal
Diffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

Thermodynamics of Giant Molecular Clouds: The Effects of Dust Grain Size

The Astrophysical Journal
The dust grain size distribution (GSD) likely varies significantly across star-forming environments in the Universe, but its impact on star formation remains unclear. This ambiguity arises because the GSD interacts nonlinearly with processes like heating,

Stardust interstellar preliminary examination, III : infrared spectroscopic analysis of interstellar dust candidates

, 2013
Under the auspices of the Stardust Interstellar Preliminary Examination, picokeystones extracted from the Stardust Interstellar Dust Collector were examined with synchrotron Fourier transform infrared (FTIR) microscopy to establish whether they contained

A Power Spectral Study of PHANGS Galaxies with JWST MIRI: On the Spatial Scales of Dust and Polycyclic Aromatic Hydrocarbons

The Astrophysical Journal
The interstellar medium (ISM) consists of a diversity of structures across a range of spatial scales, intimately tied to galactic evolution. In this work, Fourier analysis is used to characterize the spatial structures of dust and polycyclic aromatic ...
