The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase
Feng Long, Ilaria Pascucci, Adrien Houge +20
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16262756.1B (hereafter J0446B), an old (34 Myr) M4.5 star but with hints of ongoing accretion. The sp…
Water Enrichment from Pebble Drift in Disks with Gap-forming Planets
Whittney Easterwood, Anusha Kalyaan, Andrea Banzatti
Volatiles like are present as ice in solids in the outer cold regions of protoplanetary disks and as vapor in the warm inner regions within the water snow line. Icy pebbles…
Database Design for SpExoDisks: A Database & Web Portal for Spectra of Exoplanet-Forming Disks
Caleb Wheeler, Natalie R. Hinkel, Andrea Banzatti
Data access -- or the availability of new and archival data for use by the larger community -- is key for scientific advancement. How data is presented, searched, and formatted det…
JWST/MIRI detection of a carbon-rich chemistry in a solar nebula analog
Maria Jose Colmenares, Edwin Bergin, Colette Salyk +16
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their…
Retrieval of Thermally-Resolved Water Vapor Distributions in Disks Observed with JWST-MIRI
Carlos E. Romero-Mirza, Andrea Banzatti, Karin I. Öberg +13
The mid-infrared water vapor emission spectrum provides a novel way to characterize the delivery of icy pebbles towards the innermost ( au) regions of planet-forming disks. Rec…
Water in protoplanetary disks with JWST-MIRI: spectral excitation atlas and radial distribution from temperature diagnostic diagrams and Doppler mapping
Andrea Banzatti, Colette Salyk, Klaus M. Pontoppidan +19
This work aims at providing fundamental general tools for the analysis of water spectra as observed in protoplanetary disks with JWST-MIRI. We analyze 25 high-quality spectra from…
MINDS. A multi-instrument investigation into the molecule-rich JWST-MIRI spectrum of the DF Tau binary system
Sierra L. Grant, Nicolas T. Kurtovic, Ewine F. van Dishoeck +26
Most stars form in multiple systems whose properties can significantly impact circumstellar disk evolution. We investigate the physical and chemical properties of the equal-mass, s…
Mid-Infrared Spectrum of the Disk around the Forming Companion GQ Lup B Revealed by JWST/MIRI
Gabriele Cugno, Polychronis Patapis, Andrea Banzatti +5
GQ Lup B is a forming brown dwarf companion () showing evidence for an infrared excess associated with a disk surronding the companion itself. Here we present mid-i…
The Dynamic, Chimeric Inner Disk of PDS 70
Eric Gaidos, Thanawuth Thanathibodee, Andrew Hoffman +4
Transition disks, with inner regions depleted in dust and gas, could represent later stages of protoplanetary disk evolution when newly-formed planets are emerging. The PDS 70 syst…
iSLAT: the Interactive Spectral-Line Analysis Tool for JWST and beyond
Evan Jellison, Matthew Johnson, Andrea Banzatti +1
We present iSLAT (the Interactive Spectral-Line Analysis Tool), a python-based graphical tool that allows users to interactively explore and manually fit line emission observed in…
JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk
Carlos E. Romero-Mirza, Karin I. Öberg, Andrea Banzatti +24
We present MIRI MRS observations of the large, multi-gapped protoplanetary disk around the T-Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9 to 25…
Spectroastrometric Survey of Protoplanetary Disks with Inner Dust Cavities
Stanley K. Jensen, Sean D. Brittain, Andrea Banzatti +6
We present high-resolution spectra and spectroastrometric (SA) measurements of fundamental rovibrational CO emission from nine nearby (300 pc) protoplanetary disks where…
