![Vertical cut through the best-fit disk model on a logarithmic radial scale. Shown are temperatures, where the gas density, ϱdisk, exceeds an assumed ISM density of ϱISM = 2.7 × 10−24 g cm−3 (Ferrière 2001) by a factor of 1000. The snowline at Tsnow = 170 K and the 100 K-line, as well as the unity optical depth lines at a wavelength of 3.1 µm (computed for the best-fit model described in Sect. 5.2.2) measured from the star to the observer and from observer to the star, illustrate the temperature and dust density structure of the disk. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Spatial.png?resize=1200%2C715&ssl=1)

Spatial Distribution Of Water Ice In The Protoplanetary Silhouette Disk d216-0939
[astro-ph.EP] The composition of rocky planets depends on the dust in their natal protoplanetary disk (PPD), potentially containing water ice. Crystalline water ice was detected in the PPD d216-0939 in […]
![Latitude-longitude maps of column-integrated water clouds (panels a, b and c), outgoing longwave radiation (OLR, panels d, e and f) and albedo at the top of the atmosphere (TOA albedo, panels g, h and i) for Cases 2A, 2B and 2C. The variables are averaged over ∼50 orbits. The dashed white line on the albedo color bar corresponds to the surface albedo.-- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/A-broad.png?resize=1200%2C719&ssl=1)
