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…
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…
Pristine ices in a planet-forming disk revealed by heavy water

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…
Characterising the molecular line emission in the asymmetric Oph-IRS 48 dust trap: Temperatures, timescales, and sub-thermal excitation
Milou Temmink, Alice S. Booth, Margot Leemker +8
The ongoing physical and chemical processes in planet-forming disks set the stage for planet formation. The asymmetric disk around the young star Oph-IRS 48 has one of the most wel…
Volatile composition of the HD 169142 disk and its embedded planet
Luke Keyte, Mihkel Kama, Alice S. Booth +2
The composition of a planet's atmosphere is intricately linked to the chemical makeup of the protoplanetary disk in which it formed. Determining the elemental abundances from key v…
Measuring the and isotopic ratios of volatile sulfur during planet formation
Alice S. Booth, Maria N. Drozdovskaya, Milou Temmink +9
Stable isotopic ratios constitute powerful tools for unraveling the thermal and irradiation history of volatiles. In particular, we can use our knowledge of the isotopic fractionat…
ALMA high-resolution observations unveil planet formation shaping molecular emission in the PDS 70 disk
L. Rampinelli, S. Facchini, M. Leemker +7
With two directly detected protoplanets, the PDS 70 system is a unique source in which to study the complex interplay between forming planets and their natal environment. The large…
Chemistry across dust and gas gaps in protoplanetary disks: modelling the co-spatial molecular rings in the HD 100546 disk
M. Leemker, A. S. Booth, E. F. van Dishoeck +2
High-resolution observations show that typically both the dust and the gas in nearby extended protoplanetary disks are structured, possibly related to radial and azimuthal variatio…

Constraining the gas mass of Herbig disks using CO isotopologues
L. M. Stapper, M. R. Hogerheijde, E. F. van Dishoeck +7
The total disk mass sets the formation potential for exoplanets. Carbon-monoxide (CO) has been used as a gas mass tracer in T Tauri disks, but was found to be less abundant than ex…
Tracing snowlines and C/O ratio in a planet-hosting disk: ALMA molecular line observations towards the HD169142 disk
Alice S. Booth, Charles J. Law, Milou Temmink +2
The composition of a forming planet is set by the material it accretes from its parent protoplanetary disk. Therefore, it is crucial to map the chemical make-up of the gas in disks…
