Of the over 150 different molecular species detected in the interstellar and circumstellar
media, approximately 50 contain 6 or more atoms. These molecules, labeled complex by …

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 …

Context. The inner regions of the envelopes surrounding young protostars are characterized
by a complex chemistry, with prebiotic molecules present on the scales where …

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 …

Atomic and molecular data for the transitions of a number of astrophysically interesting
species are summarized, including energy levels, statistical weights, Einstein A-coefficients …

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 …

The cross-disciplinary field of astrochemistry exists to understand the formation, destruction,
and survival of molecules in astrophysical environments. Molecules in space are …

Gas-phase processes were long thought to be the key formation mechanisms for complex
organic molecules in star-forming regions. However, recent experimental and theoretical …

Context. One of the important questions of astrochemistry is how complex organic
molecules, including potential prebiotic species, are formed in the envelopes around …

Aims. The production of saturated organic molecules in hot cores and corinos is not well
understood. The standard approach is to assume that, as temperatures heat up during star …
