Our astrochemical heritage
Paola Caselli,Cecilia Ceccarelli +1 more
TL;DR: In this article, a review of the formation process of Sun-like stars in the early days of the solar system is presented, showing that three major steps are involved before the planet-formation period.

Detection of the simplest sugar, glycolaldehyde, in a solar-type protostar with alma
Jes K. Jørgensen,Cécile Favre,Suzanne E. Bisschop,Tyler L. Bourke,Ewine F. van Dishoeck,Markus Schmalzl +5 more
TL;DR: In this paper, the first detection of 13 transitions of glycolaldehyde around a solar-type young star, through Atacama Large Millimeter Array (ALMA) observations of the Class 0 protostellar binary IRAS 16293-2422 at 220 GHz (6 transitions) and 690 GHz (7 transitions).
Journal ArticleDOI
Photochemistry and Astrochemistry: Photochemical Pathways to Interstellar Complex Organic Molecules.
TL;DR: In this paper, the effects of UV radiation on the formation of complex organic molecules (COMs) in icy grain mantles are compared with those of other potential sources of radical production and chemistry in interstel...

Constraining the Abundances of Complex Organics in the Inner Regions of Solar-type Protostars
Vianney Taquet,Vianney Taquet,Ana López-Sepulcre,Ana López-Sepulcre,Ana López-Sepulcre,Cecilia Ceccarelli,Cecilia Ceccarelli,Roberto Neri,Claudine Kahane,Claudine Kahane,Steven B. Charnley +10 more
TL;DR: In this paper, the authors carried out multi-line observations of methanol and several COMs toward the two low-mass protostars NGC 1333-IRAS 2A and -IRAS 4A with the Plateau de Bure interferometer at an angular resolution of 2'', resulting in the first multilevel detection of the Obearing species glycolaldehyde and ethanol and of the N-bearing species ethyl cyanide.

A study of deuterated water in the low-mass protostar IRAS 16293-2422
Audrey Coutens,Audrey Coutens,Charlotte Vastel,Charlotte Vastel,Emmanuel Caux,Emmanuel Caux,Cecilia Ceccarelli,Sandrine Bottinelli,Sandrine Bottinelli,Laurent Wiesenfeld,Alain Faure,Yohann Scribano,Claudine Kahane +12 more
TL;DR: In this paper, a spectral survey of the source IRAS 16293-2422 was carried out in the framework of the CHESS (Chemical Herschel Surveys of Star forming regions) Herschel key program with the HIFI (Heterodyne Instrument for the Far-Infrared) instrument, allowing detection of numerous HDO lines.

Submillimeter, millimeter, and microwave spectral line catalog
Herbert M. Pickett,R. L. Poynter,Edward A. Cohen,M. L. Delitsky,J. C. Pearson,Holger S. P. Müller +5 more
TL;DR: A computer-accessible catalog of submillimeter, millimeter, and microwave spectral lines in the frequency range between 0 and 10 000 GHz (i.e. wavelengths longer than 30 μm) that has been constructed by using theoretical least-squares fits of published spectral lines to accepted molecular models.

The Cologne Database for Molecular Spectroscopy, CDMS: a useful tool for astronomers and spectroscopists
TL;DR: The Cologne Database for Molecular Spectroscopy (CDMS) as discussed by the authors contains a catalog of transition frequencies from the radio-frequency to the far-infrared region covering atomic and molecular species that (may) occur in the interstellar or circumstellar medium or in planetary atmospheres.
Journal ArticleDOI
Complex Organic Interstellar Molecules
TL;DR: In this paper, the authors discuss both the observation and chemistry of complex molecules in assorted interstellar regions in the Milky Way and discuss both their spectra and chemistry, and conclude that complex molecules are excellent probes of the physical conditions and history of the sources where they reside.
Journal ArticleDOI
The Submillimeter Array
TL;DR: The Submillimeter Array (SAA) as discussed by the authors, a collaborative project of the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics, has begun operation on Mauna Kea in Hawaii.
Journal ArticleDOI
Chemical evolution of star-forming regions
TL;DR: In this paper, the chemical processes that occur during all stages of the formation of stars, from the collapse of molecular clouds to the assemblage of icy planetesimals in protoplanetary accretion disks, are reviewed.
