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…
JWST/MIRI Finds ISM-like Amorphous Silicates in Interstellar Comet 3I/ATLAS
Matthew Belyakov, Ian Wong, Carey M. Lisse +7
We present the first spectroscopic mineralogical analysis of the dust coma of an interstellar object (ISO) from JWST mid-infrared spectroscopy of 3I/ATLAS (3I). 3I exhibits a stron…
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…
JWST-DECO: The Impact of Accretion on Mid-Infrared Observable Water in Planet-forming Disks
Jenny K. Calahan, Tarisai Dziire, Karin Öberg +13
The inner few au of a protoplanetary disk hosts the majority of observed exoplanets and is the primary planet-forming zone of the disk. The mid-IR spectra of disks, with its rich f…
JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation
María José Colmenares, Edwin A. Bergin, Ke Zhang +27
We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum (1 Myr old) source, to investigate the chemical composition and dynamical origin of i…
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
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…
Unveiling the Chemical Complexity and C/O Ratio of the HD 163296 Protoplanetary Disk: Constraints from Multi-line ALMA Observations of Organics, Nitriles, Sulfur-bearing, and Deuterated Molecules
Parashmoni Kashyap, Liton Majumdar, Edwin A. Bergin +13
The physical and chemical conditions within a protoplanetary disk play a crucial role in determining its chemical composition, which is subsequently inherited by any forming planet…
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…
Quantified Estimation of Molecular Detections across Different Classes of Neptunian Atmospheres Using Cross-Correlation Spectroscopy: Prospects for Future Extremely Large Telescopes with High-Resolution Spectrographs
Dwaipayan Dubey, Liton Majumdar, Charles Beichman +3
Neptune-size exoplanets are less studied as characterizing their atmospheres presents challenges due to their relatively small radius and atmospheric scale height. As the most comm…
Smuggling unnoticed: Towards a 2D view of water and dust delivery to the inner regions of protoplanetary discs
Adrien Houge, Sebastiaan Krijt, Andrea Banzatti +6
Infrared spectroscopy, e.g., with JWST, provides a glimpse into the chemical inventory of the innermost region of protoplanetary discs, where terrestrial planets eventually form. T…
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…
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…
