Detectability of resolved hydrogen lines from the accretion shock at gas giants and their CPDs
Gabriel-Dominique Marleau, Thomas Henning, Roy van Boekel +3
Fewer gas giants have been caught in their accretion phase than mature ones are known. Extremely Large Telescope (ELT) instruments will have a higher sensitivity and a smaller inne…
MINDS: Intertwined evolution of dust and gas in large planet-forming disks. A diversity driven by halted pebble drift?
Benoît Tabone, Milou Temmink, Laurens B. F. M. Waters +25
(Abridged) We aim to investigate the inner regions of large and massive disks orbiting T Tauri stars, thought to be progenitors of systems with wide-orbit planets and possible case…
Detecting nitrogen-carriers in the inner regions of protoplanetary disks
Marissa Vlasblom, Aditya M. Arabhavi, Niels de Klerk +3
Nitrogen is a key element for building habitable worlds, yet only a small fraction of the available N-budget of planet-forming disks has been detected. In particular, the lack of a…
JWST Edge-on Disk Ice (JEDIce): Program overview and ice survey results
Jennifer B. Bergner, Nicole Arulanantham, Emmanuel Dartois +21
The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28m spectra of five disk…
MINDS. Strong oxygen depletion in the inner regions of a very low-mass star disk?
Jayatee Kanwar, Inga Kamp, Peter Woitke +10
JWST is discovering a plethora of species in planet-forming disks around very low-mass stars such as C2H2, C6H6, C4H2, CH3 etc. The column densities of these species retrieved from…
XUE. Thermochemical Modeling Suggests a Compact and Gas-Depleted Structure for a Distant, Irradiated Protoplanetary Disk
Bayron Portilla-Revelo, Konstantin V. Getman, MarÃa Claudia RamÃrez-Tannus +14
Unveiling the physical structure of protoplanetary disk is crucial for interpreting the diversity of the exoplanet population. Until recently, the census of the physical properties…
