Extracted spectra of the investigated sources. Left: full NIRSpec spectra with major ice features labeled. The original spectra before gas emission subtraction are plotted in gray. The spectral region of the strongest HDO absorption, the O-D stretching mode, is indicated via magenta shading. The spectral region plotted on the right is indicated via gray shading. Right: a zoomed-in view of the spectral region of interest for HDO ice. -- astro-ph.SR

JWST Detections Of Amorphous And Crystalline HDO Ice Toward Massive Protostars

by Keith CowingApril 26, 2024April 26, 2024

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 […]

AFGL 2591 integrated intensity R TAdv (K km s−1 ) maps of rotational transition lines spanning a range of energy levels. The upper state energy level is indicated in the top right-hand corner and the beam size in the bottom left-hand corner. The source VLA 3 is noted by a white or black ‘x’. CH3CCH, in the first column, c-C3H2, in the second, H2CO, in the third, have contour levels of 10, 20, 30, and 40 times the noise level of the respective frequency range. CH3OH, in the fourth column, has contour levels of 10, 20, 40, 80, and 120 times the noise level of the respective frequency range. -- astro-ph.SR

Parsec Scales Of Carbon Chain And Complex Organic Molecules In AFGL 2591 And IRAS 20126

by Keith CowingAugust 21, 2023August 21, 2023

(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 […]
