- Chemistry
- 21 January 2008
Aims. A small error was recently found in the program used to compute the integrated intensities in the article Belloche et al. (2008, A&A, 482, 179). Methods. We provide new versions of Fig. 2 and…
The ALMA Protostellar Interferometric Line Survey (PILS)
- J. Jørgensen, M. Wiel, S. Wampfler

- 29 July 2016
The inner regions of the envelopes surrounding young protostars are characterised by a complex chemistry, with prebiotic molecules present on the scales where protoplanetary disks eventually may…
Increased complexity in interstellar chemistry: detection and chemical modeling of ethyl formate and n-propyl cyanide in Sagittarius B2(N)
- A. Belloche, R. Garrod, U. Cologne
- Chemistry
- 26 February 2009
Context. In recent years, organic molecules of increasing complexity have been found toward the prolific Galactic center source Sagittarius B2. Aims. We wish to explore the degree of complexity that…
Exploring Molecular Complexity with ALMA (EMoCA): Deuterated complex organic molecules in Sagittarius B2(N2)
- A. Belloche, H. Muller, R. Garrod, K. Menten
- Physics
- 18 November 2015
Deuteration is a powerful tracer of the history of the cold prestellar phase in star forming regions. Apart from methanol, little is known about deuterium fractionation of complex organic molecules…
Circumstellar molecular composition of the oxygen-rich AGB star IK Tauri - II. In-depth non-LTE chemical abundance analysis
- L. Decin, E. Beck, F. Wyrowski
- Physics
- 12 April 2010
Context. The interstellar medium is enriched primarily by matter ejected from evolved low and intermediate mass stars. The outflow from these stars creates a circumstellar envelope in which a rich…
Ubiquitous Argonium, ArH⁺, in the Diffuse Interstellar Medium

- Physics
- 31 March 2014
ArH+ is isoelectronic with HCl. The J = 1-0 and 2-1 transitions of 36ArH+ near 617.5 and 1234.6 GHz, respectively, have been identified very recently as emission lines in spectra obtained with…
The ALMA-PILS survey: isotopic composition of oxygen-containing complex organic molecules toward IRAS 16293–2422B
- J. Jørgensen, H. Muller, S. Wampfler
- PhysicsAstronomy & Astrophysics
- 27 August 2018
Context. One of the important questions of astrochemistry is how complex organic molecules, including potential prebiotic species, are formed in the envelopes around embedded protostars. The…
Exploring molecular complexity with ALMA (EMoCA): Alkanethiols and alkanols in Sagittarius B2(N2)
- H. Muller, A. Belloche, K. Menten
- Chemistry
- 16 December 2015
Context. Over the past five decades, radio astronomy has shown that molecular complexity is a natural outcome of interstellar chemistry, in particular in star forming regions. However, the pathways…
