![Integrated intensity maps of the 1.7 mm continuum, 183 GHz water line, and three methanol lines in the HD 100546 (top row) and IRS 48 (bottom row) disks. White contours highlight the inner dust ring of HD 100546 and the asymmetric mm-crescent of IRS 48 from their continuum maps, pink contours show 3, 4, and 5σ levels. The white ellipse in the bottom left of each panel shows the beam.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/An-ALMA.png?resize=1200%2C697&ssl=1)
[astro-ph.EP] Water and methanol are the fundamental constituents of interstellar and cometary ices: understanding their abundances in disks is therefore of high importance to reveal how this ice reservoir evolves […]
