The robust detection and spatial distribution of acetaldehyde in Orion KL: ALMA observations and chemical modeling

Miwha Jin, Anthony J. Remijan, Robin T. Garrod +5

Despite the organic molecule inventory detected in Orion KL, acetaldehyde (CH3CHO) -- one of the most ubiquitous interstellar aldehydes -- has not been firmly identified with mm-wa…

FAUST XIX. DCO in the outflow cavities of NGC\,1333 IRAS\,4A: recovering the physical structure of its original prestellar core

Layal Chahine, Cecilia Ceccarelli, Marta De Simone +25

Molecular deuteration is a powerful diagnostic tool for probing the physical conditions and chemical processes in astrophysical environments. In this work, we focus on formaldehyde…

Deep Search for Glycine Conformers in Barnard 5

Tadeus Carl, Eva Wirström, Per Bergman +3

One of the most fundamental hypotheses in astrochemistry and astrobiology states that crucial biotic molecules like glycine (NHCHCOOH) found in meteorites and comets are in…

Isotopic Evidence for a Cold and Distant Origin of the Interstellar Object 3I/ATLAS

Martin Cordiner, Nathan X. Roth, Marco Micheli +16

Interstellar objects provide the only directly observable samples of icy planetesimals formed around other stars, and can therefore provide insight into the diversity of physical a…

An Enriched Methane D/H Ratio in the Interstellar Object 3I/ATLAS

Nathan X. Roth, Martin Cordiner, Stefanie Milam +15

Interstellar objects are interlopers from other planetary systems, and their volatile compositions provide a glimpse into planet formation around their host star. We present near-i…

Multiple chemical tracers finally unveil the intricate NGC\,1333 IRAS\,4A outflow system. FAUST XVI

Layal Chahine, Cecilia Ceccarelli, Marta De Simone +54

The exploration of outflows in protobinary systems presents a challenging yet crucial endeavour, offering valuable insights into the dynamic interplay between protostars and their…

FAUST III. Misaligned rotations of the envelope, outflow, and disks in the multiple protostellar system of VLA 16232417

Satoshi Ohashi, Claudio Codella, Nami Sakai +69

We report a study of the low-mass Class-0 multiple system VLA 1623AB in the Ophiuchus star-forming region, using HCO (), CS (), and CCH () lines as…

Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Planetary and Cometary Atmospheres

Martin A. Cordiner, Alexander E. Thelen, Thibault Cavalié +26

The study of planets and small bodies within our Solar System is fundamental for understanding the formation and evolution the Earth and other planets. Compositional and meteorolog…

FAUST II. Discovery of a Secondary Outflow in IRAS 15398-3359: Variability in Outflow Direction during the Earliest Stage of Star Formation?

Yuki Okoda, Yoko Oya, Logan Francis +66

We have observed the very low-mass Class 0 protostar IRAS 15398-3359 at scales ranging from 50 au to 1800 au, as part of the ALMA Large Program FAUST. We uncover a linear feature,…
