First Detection of HC5N in a Class II Disk around TW Hya
Steven C. Wampler, Ryan A. Loomis, Amina Diop +9
Over the last decade of ALMA's operation the molecular inventory of protoplanetary disks has expanded rapidly, revealing a diverse set of nitrogen-bearing organics and carbon-chain…
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…
Methanol emission tracing ice chemistry and dust evolution in the TW Hya protoplanetary disk
John D. Ilee, Catherine Walsh, Jenny C. Calahan
Methanol (CHOH) ice is abundant in space and is a key feedstock for seeding chemical complexity in interstellar and circumstellar environments. Despite its ubiquity, gas-phas…
Linking planet formation to exoplanet characteristics: C/O as a diagnostic of planet formation
Catherine Walsh
Gas-giant exoplanets are test cases for theories of planet formation as their atmospheres are proposed to carry signatures of their formation within the protoplanetary disk. The me…
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…
ALMA reveals thermal and non-thermal desorption of methanol ice in the HD 100546 protoplanetary disk
Lucy Evans, Alice S. Booth, Catherine Walsh +8
Methanol (CHOH) and formaldehyde (HCO) are chemically coupled organic molecules proposed to act as an intermediate step between simple molecules and more complex prebiotic…
