Hunting for methanol in the water rich, planet forming disk around HL Tau
Alessandro Soave, Margot Leemker, Stefano Facchini +3
Methanol, the simplest complex organic molecule found in space, is considered a key compound necessary for the formation of chemical species of prebiotic interest. Methanol detecti…
Zooming into the water snowline: high resolution water observations of the HL Tau disk
M. Leemker, S. Facchini, P. Curone +4
Water is one of the central molecules for the formation and habitability of planets. In particular, the region where water freezes-out, the water snowline, could be a favorable loc…
The chemical diversity of giant-planet nurseries as revealed by ALMA
Alice S. Booth, Jenny Calahan, Milou Temmink +9
With the giant exoplanet occurrence rate peaking around stars of 1.5-2 solar masses, there is strong motivation to characterize the disks that set their formation conditions. Obser…
Pristine ices in a planet-forming disk revealed by heavy water
Margot Leemker, John J. Tobin, Stefano Facchini +4
Water is essential to our understanding of the planet-formation process and habitability on Earth. Although trace amounts of water are seen across all phases of star and planet for…
Ice sublimation in the dynamic HD 100453 disk reveals a rich reservoir of inherited complex organics
Alice S. Booth, Lisa Wölfer, Milou Temmink +7
Protoplanetary disks around luminous young A-type stars are prime observational laboratories to determine the abundances of complex organic molecules (COMs) present during planet f…
Radial variations in nitrogen, carbon, and hydrogen fractionation in the PDS 70 planet-hosting disk
L. Rampinelli, S. Facchini, M. Leemker +8
Element isotopic ratios are powerful tools to reconstruct the journey of planetary material, from the parental molecular cloud to protoplanetary disks, where planets form and accre…
