![Column density maps of 13CO2, CO and OCN− ice (panel I, II and III, respectively). 12CO2 column densities are derived from 13CO2 column densities. Panel IV shows the ratio between the 4.38 µm and 4.39 µm peak of the 13CO2 ice feature. A higher ratio indicates higher degree of CO2 ice segregation. The axes are shown on astronomical unit scales. Pixelated areas especially in the north and south of the maps as well as the edges are caused by low signal-to-noise levels. -- [astro-ph.SR]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Mapping.png?resize=1200%2C718&ssl=1)
[astro-ph.SR] The composition of planets and their atmospheres is largely determined by the formation environment of the planet. This environment is pre-determined during early stages when the protostar is still […]

JWST Detections Of Amorphous And Crystalline HDO Ice Toward Massive Protostars
This work aims to utilize the increased sensitivity and resolution of the JWST to quantify the HDO/H2O ratio in ices toward young stellar objects (YSOs) and to determine if the […]

Parsec Scales Of Carbon Chain And Complex Organic Molecules In AFGL 2591 And IRAS 20126
(Abridged) There is a diverse chemical inventory in protostellar regions leading to the classification of extreme types of systems. Warm carbon chain chemistry sources, for one, are the warm and […]
