The JDISC Survey: Inner Disk Chemistry of Class I/FS Disks and Tentative Evidence for Early Pebble Drift
Ke Zhang, Andrea Banzatti, Colette Salyk +22
We present the first chemical survey of Class I and Flat-Spectrum (I/FS) disks using JWST MIRI/MRS, targeting sixteen sources in the Ophiuchus star-forming region. Through empirica…
ESO User Support and Observation Preparation for VLTI Science Operations
M. Wittkowski, G. Beccari, A. Corporaal +15
The paper describes recent user‑focused upgrades to the VLTI, including new guiding and instrument modes, enhanced observation‑planning tools, and the availability of reduced GRAVI…
Far-ultraviolet flux distribution in Orion and its relation to stellar accretion
Rossella Anania, Andrew J. Winter, Miguel Vioque +8
Orion is the closest region hosting active star formation and young OBA stars. Computing far-ultraviolet (FUV) fluxes at its stars is essential to connect stellar and protoplanetar…
ESOFinder: an LLM-powered tool to help users navigate ESO documentation
P. Sánchez-Sáez, C. Reinero, M. Vioque +6
The large amount and diversity of documentation available for users of the European Southern Observatory (ESO), spanning the full observing lifecycle from proposal preparation and…
From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius
Chengyan Xie, Ilaria Pascucci, Feng Long +23
We present JWST/MIRI spectroscopy of 14 disks in the older (~5-10 Myr) Upper Scorpius (USco) association and use slab of gas in local thermal equilibrium to infer basic gas propert…
Chemical Divergence and Water Depletion: Gas Properties of Evolved Upper Scorpius Disks Revealed by JWST/MIRI
Eshan Raul, Ke Zhang, Abygail Waggoner +25
Tracing the chemical evolution of protoplanetary disks over time requires observations of disks at different ages. However, most JWST/MIRI surveys published to date have targeted y…
