Observational evidence for a possible link between PAH emission and dust trap locations in protoplanetary disks
Nienke van der Marel, Niels F. W. Ligterink, Ryan van der Werf +4
Polycyclic Aromatic Hydrocarbons (PAHs) are commonly detected in protoplanetary disks, but it is unclear what causes the wide range of intensities across the samples. In this work,…
The rapid formation of macromolecules in irradiated ice of protoplanetary disk dust traps
Niels F. W. Ligterink, Paola Pinilla, Nienke van der Marel +4
Organic macromolecular matter is the dominant carrier of volatile elements such as carbon, nitrogen, and noble gases in chondrites -- the rocky building blocks from which Earth for…
Evidence for Abiotic Dimethyl Sulfide in Cometary Matter
Nora Hänni, Kathrin Altwegg, Michael Combi +5
Technological progress related to astronomical observatories such as the recently launched James Webb Space Telescope (JWST) allows searching for signs of life beyond our Solar Sys…
Volatiles in the HO and CO ices of comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Jean-Jacques Berthelier +11
ESA's Rosetta spacecraft at comet 67P/Churyumov-Gerasimenko (67P) was the first mission that accompanied a comet over a substantial fraction of its orbit. On board was the ROSINA m…
A major asymmetric ice trap in a planet-forming disk IV. Nitric oxide gas and a lack of CN tracing sublimating ices and a C/O ratio
M. Leemker, A. S. Booth, E. F. van Dishoeck +5
[Abridged] Most well-resolved disks observed with ALMA show signs of dust traps. These dust traps set the chemical composition of the planet forming material in these disks, as the…
The (w)hole survey: an unbiased sample study of transition disk candidates based on Spitzer catalogs
Nienke van der Marel, Bart W. Verhaar, Sierk van Terwisga +4
Understanding disk evolution and dissipation is essential for studies of planet formation. Transition disks, i.e., disks with large dust cavities and gaps, are promising candidates…
