Epsilon Canis Majoris: The Brightest Extreme-ultraviolet Source with Surprisingly Low Interstellar Absorption

The Astrophysical Journal
The B2 star Epsilon Canis Majoris ( ϵ CMa), at parallax distance d = 124 ± 2 pc, dominates the H i photoionization of the Local Interstellar Cloud. At its closer parallax distance compared to previous estimates, ϵ CMa has a 0.9 mag fainter absolute ...

Photometry and Classification of Stars in the Direction of the Dark Cloud TGU 619 in Cepheus. II. Interstellar Extinction and Cloud Distance

Open Astronomy, 2011
Interstellar extinction is investigated in a 1.5 square degree area of the Cepheus Flare in the direction of the dark cloud TGU 619 at ℓ=102.5°, b=+15.5°.

Discovery of Thionylimide, HNSO, in Space: The first N-, S-, and O-bearing Interstellar Molecule

The Astrophysical Journal Letters
We present the first detection in space of thionylimide (HNSO) toward the Galactic center molecular cloud G + 0.693-0.027, thanks to the superb sensitivity of an ultradeep molecular line survey carried out with the Yebes 40 m and IRAM 30 m telescopes ...

The early evolution of the solar system [PDF]

The problems of relating collapse conditions in an interstellar cloud to a model of the primitive solar nebula are discussed. In such a nebula there is a radial force balance between gravity, the pressure gradient, and centrifugal forces due to the ...

Unusual relative strengths of the diffuse interstellar bands in some interstellar dust clouds [PDF]

Some of the diffuse interstellar features (DIBs) in the spectra of certain stars at high galactic latitudes (1 is greater than 15 degrees) are unusually weak or absent while others have the strength expected for their color excess.

Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects

Universe
The disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...
