Cometary nuclei contain the least modified material from the formative epoch of our
planetary system, and their compositions reflect a range of processes experienced by …

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

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 …

The BASECOL2012 database is a repository of collisional data and a web service within the
Virtual Atomic and Molecular Data Centre (VAMDC, http://www. vamdc. eu). It contains rate …

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 …

Isotopic ratios in comets provide keys for the understanding of the origin of cometary
material, and the physical and chemical conditions in the early Solar Nebula. We review …

Context. We model the dust and free-free continuum emission in the high-mass star-forming
region Sagittarius B2. Aims. We want to reconstruct the 3D density and dust temperature …

The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is a Chinese
megascience project funded by the National Development and Reform Commission (NDRC) …

Aims. We describe the assignment of a previously unidentified interstellar absorption line to
ArH+ and discuss its relevance in the context of hydride absorption in diffuse gas with a low …

Context. Unbiased spectral surveys are powerful tools to study the chemistry and the physics
of star forming regions, because they can provide a complete census of the molecular …
