Diffuse interstellar clouds associated with dark clouds

The Astrophysical Journal, 1982
Measurements of CH emission at 9 cm toward the bright stars ..cap alpha.. Cam and kappa Cas and from dark clouds near the stars reveal an association between diffuse clouds and dark clouds. Here the term diffuse clouds refers to clouds seen in optical absorption; the term dark clouds refers to opaque regions on the Palomar Sky Survey observed through ...

Earth's Mesosphere During Possible Encounters With Massive Interstellar Clouds 2 and 7 Million Years Ago

Geophysical Research Letters
Our solar system's path has recently been shown to potentially intersect dense interstellar clouds 2 and 7 million years ago: the Local Lynx of Cold Cloud and the edge of the Local Bubble.

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 ...

Gas Kinematics and Dynamics of Carina Pillars: A Case Study of G287.76-0.87

The Astrophysical Journal
We study the kinematics of a pillar, namely G287.76-0.87, using three rotational lines of ^12 CO(5-4), ^12 CO(8-7), ^12 CO(11-10), and a fine structure line of [O i ] 63 μ m in southern Carina observed by SOFIA/GREAT.
