How leaky? A large parameter study of leaky dust traps to quantify the transport of pebbles and ice in protoplanetary discs
Adrien Houge, Anders Johansen, Andrea Banzatti +1
In protoplanetary discs, the presence of dust traps can significantly alter the transport of solids from the outer to the inner regions, and hence they are often invoked as an expl…
HO in the terrestrial planet-forming regions of protoplanetary disks
Colette Salyk, Klaus M. Pontoppidan, Ke Zhang +12
Isotopologues play an important role in solar system cosmochemistry studies, revealing details of early planet formation physics and chemistry. Oxygen isotopes, as measured in sola…
Protoplanetary disk cavities with JWST-MIRI: a dichotomy in molecular emission

The evolution of planet-forming regions in protoplanetary disks is of fundamental importance to understanding planet formation. Disks with a central deficit in dust emission, a "ca…
Cosmic cascades: How disk substructure regulates the flow of water to inner planetary systems
Sebastiaan Krijt, Andrea Banzatti, Ke Zhang +17
The influx of icy pebbles to the inner regions of protoplanetary disks constitutes a fundamental ingredient in most planet formation theories. The observational determination of th…

JWST's sharper view of EX Lup: cold water from ice sublimation during accretion outbursts
Sarah A. Smith, Carlos E. Romero-Mirza, Andrea Banzatti +9
The unstable accretion phases during pre-main-sequence evolution of T Tauri stars produce variable irradiation and heating of planet-forming regions. A strong accretion outburst wa…
Smuggling unnoticed: Towards a 2D view of water and dust delivery to the inner regions of protoplanetary discs
