Impact of Protostellar Outflow on Star Formation: Effects of Initial Cloud Mass

, 2011
Star formation efficiency controlled by the protostellar outflow in a single cloud core is investigated by three-dimensional resistive MHD simulations. Starting from the prestellar cloud core, the star formation process is calculated until the end of the

Organic Chemistry in the H2-bearing, CO-rich Interstellar Ice Layer at Temperatures Relevant to Dense Cloud Interiors

The Astrophysical Journal
Ice chemistry in the dense, cold interstellar medium (ISM) is probably responsible for the formation of interstellar complex organic molecules (COMs). Recent laboratory experiments performed at T ∼ 4 K have shown that irradiation of CO:N _2 ice samples ...

The Fractal Dimension of Projected Clouds

, 2005
The interstellar medium seems to have an underlying fractal structure which can be characterized through its fractal dimension. However, interstellar clouds are observed as projected two-dimensional images, and the projection of a tri-dimensional fractal

A search for interstellar anthracene toward the Perseus anomalous microwave emission region

, 2010
We report the discovery of a new broad interstellar (or circumstellar) band at 7088.8 +- 2.0 \AA coincident to within the measurement uncertainties with the strongest band of the anthracene cation (C$_{14}$H$_{10}$$^+$) as measured in gas-phase ...

Anomalous Neutral Hydrogen Column Densities in Local Interstellar Medium Clouds

The Astrophysical Journal
Analysis of high-resolution spectra of the hydrogen and deuterium Ly α lines provides measurements of interstellar neutral hydrogen column densities N (H i ) to 113 stars within 50 pc of the Sun. Plots of N (H i ) versus distance through the LIC, G, Mic,

Cloud-cloud collisions in the interstellar medium

The Astrophysical Journal, 1980
Results are presented from time-dependent numerical simulations of cloud-cloud collisions in the interstellar medium. Special emphasis is placed on physically detailed models of cloud collisions. The numerical simulations include heating, cooling, thermal conductivity, self-gravity, and molecule formation; magnetic fields have been neglected.

Is the Sun Embedded in a Typical Interstellar Cloud?

, 2008
The physical properties and kinematics of the partially ionized interstellar material near the Sun are typical of warm diffuse clouds in the solar vicinity.

Organic Molecules in Translucent Interstellar Clouds [PDF]

Origins of Life and Evolution of Biospheres, 2014
Absorption spectra of translucent interstellar clouds contain many known molecular bands of CN, CH+, CH, OH, OH(+), NH, C2 and C3. Moreover, one can observe more than 400 unidentified absorption features, known as diffuse interstellar bands (DIBs), commonly believed to be carried by complex, carbon-bearing molecules.
