Star-forming regions show a rich and varied chemistry, including the presence of complex
organic molecules—in both the cold gas distributed on large scales and the hot regions …

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 …

Context. Water is a key molecule in the physics and chemistry of star and planet formation,
but it is difficult to observe from Earth. The Herschel Space Observatory provided …

Water is a fundamental molecule in the universe. On Earth, water exists in all three phases:
gas, liquid, and solid (ice). Liquid water facilitates many chemical reactions as a solvent …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

ABSTRACT Water In Star-forming regions with Herschel (WISH) is a key program on the
Herschel Space Observatory designed to probe the physical and chemical structures of …

Aims. As a part of the CALYPSO Large Program, we aim to constrain the properties of
protostellar jets and outflows by searching for corresponding emission in a sample of 21 …

1.1. Interstellar Clouds and Interstellar Chemistry A space between stars is not completely a
vacuum, but is filled up with interstellar gas, whose average number density of H nuclei in all …

We present the first census of the interstellar Complex Organic Molecules (iCOMs) in the low-
mass Class I protostar SVS13-A, obtained by analysing data from the IRAM-30 m Large …

We present a publicly available, open source version of the time-dependent, gas-grain
chemical code UCLCHEM. UCLCHEM propagates the abundances of chemical species …
