Interstellar Extinction in the Direction of The Barnard 1 Dark Cloud in Perseus [PDF]
Open Astronomy, 2003 AbstractSpectral and luminosity classes, absolute magnitudes, color excesses, interstellar extinctions and distances are determined for 98 stars down to 18 mag in the Barnard 1 dark cloud belonging to the Per OB2 association. The classification of stars is based on their photoelectric photometry in the Vilnius seven-color photometric system.

A study of the nine interstellar dark clouds
Astrophysical Journal, Supplement Series, 1981 An investigation of the physical and chemical properties of nine interstellar dark clouds is reported. Observations of a variety of atomic and molecular species have been obtained and the clouds have been partially mapped in the near infrared. The observations have been compared with theoretical models of the line emission and absorption from ...

The Chemistry of Cold, Dark Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1987 In recent years the nearby cold, dark clouds have been shown to possess a rich chemistry, with interesting differences with respect to warmer massive-star-forming regions and also among the cold clouds themselves. 39 molecular species are now known in these regions.

Interstellar chemistry of nitrogen hydrides in dark clouds [PDF]
Astronomy & Astrophysics, 2013 The aim of the present work is to perform a comprehensive analysis of the interstellar chemistry of nitrogen, focussing on the gas-phase formation of the smallest polyatomic species and in particular nitrogen hydrides. We present a new chemical network in which the kinetic rates of critical reactions have been updated based on recent experimental and ...

The dark side of interstellar clouds
, 2005 The comparison of HI, CO, dust, and gamma-ray maps in the solar neighborhood has led to the discovery of large amounts of dark gas not traced in HI and CO at the transition between the two phases.
