Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

Cold dark clouds are nearby members of the densest and coldest phase in the Galactic
interstellar medium, and represent the most accessible sites where stars like our Sun are …

The evolution of star-forming regions and their thermal balance are strongly influenced by
their chemical composition, which, in turn, is determined by the physicochemical processes …

Aims. The large quantity and high quality of modern radio and infrared line observations
require efficient modeling techniques to infer physical and chemical parameters such as …

Context. Core condensation is a critical step in the star-formation process, but it is still poorly
characterized observationally. Aims. We have studied the 10 pc-long L1495/B213 complex …

ABSTRACT The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a
high-resolution infrared spectroscopic survey spanning all Galactic environments (ie, bulge …

We present the results of chemical modeling of complex organic molecules (COMs) under
conditions typical for prestellar cores. We utilize an advanced gas-grain astrochemical …

Aims. Photodissociation by UV light is an important destruction mechanism for carbon
monoxide (CO) in many astrophysical environments, ranging from interstellar clouds to …

The disks that surround young stars are mostly composed of molecular gas, which is harder
to detect and interpret than the accompanying dust. Disk mass measurements have …

We present results of an extensive mapping survey of N 2 H+(1–0) in about 60 low-mass
cloud cores already mapped in the NH 3 (1, 1) inversion transition line. The survey has been …
