CORINOS IV: Quantifying Baseline-Fitting Uncertainties in SO Ice Measurements with JWST/MIRI
Rachel E. Gross, Yao-Lun Yang, L. Ilsedore Cleeves +15
Sulfur dioxide (SO) ice has been tentatively detected in protostellar envelopes, but its reliability as a solid-state sulfur reservoir remains unclear. We present new measureme…
Cosmic dust as a prerequisite for the formation of complex organic molecules in space?
Alexey Potapov, Kilian Pollok, Falko Langenhorst +2
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and r…
Is cosmic dust porous?
Alexey Potapov, Martin R. S. McCoustra, Ryo Tazaki +4
There is a long-standing discussion in the astrophysical/astrochemical community as to the structure and morphology of dust grains in various astrophysical environments (e.g., inte…
First Detections of PN, PO, and PO+ toward a Shocked Low-mass Starless Core
Samantha Scibelli, Andrés MegÃas, Izaskun Jiménez-Serra +6
Phosphorus is a key element that plays an essential role in biological processes important for living organisms on Earth. The origin and connection of phosphorus-bearing molecules…
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…
CORINOS. III. Outflow Shocked Regions of the Low-mass Protostellar Source IRAS 15398-3359 with JWST and ALMA
Yuki Okoda, Yao-Lun Yang, Neal J. Evans +10
While molecular outflows have been studied in details with radio interferometry, observations of the hotter gas in protostellar outflows at a comparable physical scale is often cha…
