Composite image of a star-forming region (left) and Comet 67P (right). In the center is the ammonium hydrosulfide salt (NH4SH) that both appear to have in common, and which explains, among other things, why there is less volatile sulfur in star-forming regions than expected.

H2 number density (left) and gas temperature (right) in the adopted physical structure for the HOPS-370 disk based on modeling by Tobin et al. (2020a). The contours in the left panel start at 5 × 108 cm−3 (white) and increase by 1 dex per contour. The (vertically isothermal) contours in the right-hand panel show the gas temperature at different radii in the disk. -- astro-ph.EP

The experimental far-infrared spectrum (top) of CH2DSH showing the Q-branch of three intrastate (∆νt=0) torsional subbands, near 27.2 cm−1 , and two interstate (∆νt=±1) torsional subbands near 26.75 cm−1 and 27.6 cm−1 . The calculated spectrum (bottom) emphasizes the strong overlap between bands, especially near 27.2 cm−1 . Calculated transitions are colour coded with red, blue, and green indicating that their lower torsional state is e0, o1, and e1, respectively. -- astro-ph.GA
