DEMOS. II. What the full Lupus demographics truly tell us about protoplanetary disc evolution

Lorenzo A. Malanga, Giovanni P. Rosotti, Giuseppe Lodato +7

Assessing whether disc evolution is driven by viscosity or MHD winds is crucial to determine the conditions in which planets form. The rich statistical information encoded in nearb…

DEMOS I. A Bayesian inference framework to constrain disc evolution from observed demographics

Lorenzo A. Malanga, Giovanni P. Rosotti, Giuseppe Lodato +3

The mechanism driving the evolution and dispersal of protoplanetary discs has a substantial impact on the theories of planet formation. To date, neither the viscous paradigm nor th…

Impact of accretion variability on the CO emission of a disk around a very-low-mass star with JWST

C. Bergez-Casalou, B. Tabone, Y. Aoyama +14

Studying the structure of very-low-mass stars () protoplanetary disk is crucial to understand the formation of Earth-like planets. In this paper, we characteriz…

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…

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…

Molecular Similarity and Water Diversity in Coeval Binary Disks: JWST/MIRI Observations of Sz 65 and Sz 66

Jinghuai Yao, Ke Zhang, Andrea Banzatti +10

We present JWST/MIRI Medium Resolution Spectrometer spectra of the wide-separation (projected separation au) binary protoplanetary disks Sz 65 (K7; ) and Sz…

MINDS: Complementary inclinations in the binary system HK Tau reveal gas- and ice-phase chemistry

Alice Somigliana, Giulia Perotti, Nicolás T. Kurtovic +18

[Abridged] HK Tau is a roughly equal mass pre-main sequence binary system consisting of a low-inclination primary (57 deg) and an edge-on (83 deg) secondary. We present JWST/MIRI o…

Chemistry and IR emission of acetylene in planet-forming regions of T Tauri disks. Impact of elemental abundances and dust properties

Pacôme Estève, Benoît Tabone, Emilie Habart +5

(Abridged) We aim to explore the parameters that influence the mid-infrared emission of CH and HO, and if the spread observed in / is tr…

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…

Molecular diagnostics for the mid-infrared emission of planet-forming disks. Carbon and oxygen elemental abundances

Aditya M. Arabhavi, Inga Kamp, Ewine F. van Dishoeck +8

Mid-infrared observations of planet-forming disks reveal a wide diversity in molecular spectra. Carbon and oxygen abundances play a central role in setting the chemical environment…

Protoplanetary disk cavities with JWST-MIRI: a dichotomy in molecular emission

Patrick Mallaney, Andrea Banzatti, Colette Salyk +24

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…
