Gas and Dust in Interstellar Clouds [PDF]

Symposium - International Astronomical Union, 1973
Detailed measurements have been made of the H, OH and H2CO lines formed in the L1534 dense dust cloud; some H and H2CO observations have been made of the dust cloud lying behind the Orion cluster. These indicate a similar distribution of the 3 species throughout the dust clouds.

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 ...

Orbital evolution under action of fast interstellar gas flow

, 2010
Orbital evolution of an interplanetary dust particle under action of an interstellar gas flow is investigated. Secular time derivatives of the particle orbital elements, for arbitrary orbit orientation, are presented. An important result concerns secular

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,

Interstellar Dust and Gas in the Heliosphere

Journal of Physics: Conference Series, 2020
Abstract Interstellar dust and gas that enter the heliosphere provide us with important clues about both the heliosphere and the local interstellar medium (LISM). The picture we have of the LIC from both in situ detections and absorption line data presents questions that have important implications for the origins and evolution of the ...

Silicate Extinction Profile Based on the Stellar Spectrum by Spitzer/IRS

The Astrophysical Journal
The 9.7 and 18 μ m interstellar spectral features, arising from the Si–O stretching and O–Si–O bending modes of amorphous silicate dust, are the strongest extinction features in the infrared.

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 ...
