The environments forming stellar and planetary systems
Michael Kuffmeier, Jaime E. Pineda, Peter Schilke +29
How does a star's birth environment set the mass, angular momentum and chemical complexity delivered to its planet-forming disk, and thereby whether it builds planets, brown dwarfs…
Chemical Demographics of Star-forming Regions
Maria N. Drozdovskaya, Timea Csengeri, Maria Teresa Beltrán +35
Our understanding of complex organic chemistry during the formation of stars and planets is shaped by a handful of cherry-picked sources with bright molecular emission lines. This…
Chemistry on solar system scales
Catherine Walsh, Maria Drozdovskaya, Dmitry Semenov +33
The initial chemical composition of planets, primitive bodies in our solar system, and exoplanets is ultimately set by their nascent protoplanetary disks. Yet observing key carbon-…
Planetary system architectures in the final stages of planet formation
Patricia Luppe, Zoe Roumeliotis, Sebastian Marino +18

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) 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) 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…
