Complex Organic Molecules in Protostars with ALMA Spectral Surveys (COMPASS) VIII. First interstellar detection of fully deuterated methyl cyanide

A. Belloche, J. K. Jørgensen, M. N. Drozdovskaya +12

Deuteration is a powerful metric to gain insight into the formation pathways of interstellar molecules in star forming regions. Our primary goal is to search for the fully deuterat…

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) VI. Discovery of a class I methanol maser transition and its association with acetaldehyde

Jae-Hong Jeong, Jeong-Eun Lee, Jes K. Jørgensen +16

CH3OH masers that are collisionally pumped, referred to as `class I', commonly trace shock interfaces in star-forming regions, but their incidence in low-mass protostars remains po…

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) VII. First interstellar detection of fully deuterated methanol

A. Belloche, S. Spezzano, A. Coutens +12

There have been no robust identifications of fully deuterated methanol, CD3OD, in the interstellar medium (ISM) to date. Our goal is continue the search for CD3OD in star-forming r…

The SOFIA Massive (SOMA) Star Formation Survey. V. Clustered Protostars

Zoie Telkamp, Ruben Fedriani, Jonathan C. Tan +16

We present m SOFIA-FORCAST images of seven regions of ``clustered" star formation as part of the SOFIA Massive (SOMA) Star Formation Survey. We identify a total of 34…
