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 ...

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 ...

The Passage of the Solar System through the Edge of the Local Bubble

The Astrophysical Journal
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

Molecular Formation in Low-Metallicity Hot Cores

Universe
The chemical complexity in low-metallicity hot cores has been confirmed by observations. We investigate the effect of varying physical parameters, such as temperature, density and the cosmic ray ionisation rate (CRIR), on the molecular abundance ...
