Sulphur-bearing molecule survey towards prestellar and starless cores in the Perseus molecular cloud

J. Ferrer Asensio, S. Scibelli, A. Pokorny-Yadav +7

Sulphur is drastically depleted from the gas phase in dense starless and prestellar cores, creating the long-standing "missing sulphur problem". Observations of sulphur-bearing mol…

Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) -- IV. Methyl cyanide isotopologues toward BHR71-IRS1

P. Nazari, A. Coutens, J. K. Jørgensen +16

Methyl cyanide is one of the most abundant nitrogen-bearing complex organic molecules observed in the gas phase around low- and high-mass protostars. However, very few observations…

Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) II. Approach to data reduction and products for line-rich broadband (sub)millimeter spectra

Adele L. Plunkett, Sébastien Maret, Daniel Harsono +26

Studying the chemical composition of the warm gas surrounding embedded solar-type protostars is one of the areas for which the Atacama Large Millimeter/submillimeter Array (ALMA) i…

Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS): I. Overview of the ALMA Large Program

J. K. Jørgensen, A. Coutens, M. N. Drozdovskaya +27

It remains a fundamental research question in astrochemistry to characterize the inventory of complex organic molecules formed during the early stages of star formation, which may…

Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) III. CHOH isotopic fractionation in the low-mass protostar BHR71-IRS1

A. Coutens, F. Cruz-Sáenz de Miera, J. K. Jørgensen +26

[Abridged] Methanol is a complex organic molecule detected in both ice and gas toward star-forming regions. Due to its high abundance, its rarer isotopologues, including the deuter…

Gas phase Elemental abundances in Molecular cloudS (GEMS) XII. First look into the para-to-ortho ratio of c-C3D2 towards prestellar cores

J. Ferrer Asensio, A. Fuente, E. Roueff +3

Symmetric molecules with identical nuclei form distinct nuclear spin isomers (ortho and para) that cannot interconvert via radiative or inelastic transitions, preserving clues abou…

Inventories of Rich Carbon-Chain Chemistry in Prestellar and Starless Cores in the Perseus Molecular Cloud

Anissa Pokorny-Yadav, Samantha Scibelli, Judit Ferrer Asensio +3

Carbon-chain molecules serve as an important reservoir of reactive organic matter that will eventually be incorporated into protoplanetary disks, planets, and cometary material. Pr…

c-C3H2 deuteration towards prestellar and starless cores in the Perseus Molecular Cloud

J. Ferrer Asensio, S. Scibelli, L. Steffes +6

Deuterium fractionation becomes highly efficient in cold, dense cores where CO is frozen out. Cyclopropenylidene (c-C3H2), an early-formed carbon ring, and its deuterated isotopolo…

Nascent chemical complexity in prestellar core IRAS 16293E: complex organics and deuterated methanol

Samantha Scibelli, Maria N. Drozdovskaya, Paola Caselli +5

Prestellar cores represent early sites of low-mass ( few M) star and planet formation and provide insight into initial chemical conditions of complex organic mole…

Fractionation in young cores: Direct determinations of nitrogen and carbon fractionation in HCN

S. S. Jensen, S. Spezzano, P. Caselli +4

We aim to determine the N/N and C/C ratios for HCN in six starless and prestellar cores and compare the results between the direct method using radiativ…

A deep search for large complex organic species toward IRAS16293-2422 B at 3 mm with ALMA

P. Nazari, J. S. Y. Cheung, J. Ferrer Asensio +14

Complex organic molecules (COMs) have been detected ubiquitously in protostellar systems. However, at shorter wavelengths (~0.8mm) it is more difficult to detect larger molecules t…

Tracing the contraction of the pre-stellar core L1544 with HCO = 1-0 emission

J. Ferrer Asensio, S. Spezzano, P. Caselli +6

Spectral line profiles of several molecules observed towards the pre-stellar core L1544 appear double-peaked. For abundant molecular species this line morphology has been linked to…
