JWST-DECO: Temporal Variations in the Mid-IR Silicate Features of Two T Tauri Discs Based on Spitzer and JWST observations
N. Sameshima, T. Miyata, T. Kamizuka +9
Mid-infrared spectra of planet-forming discs commonly show prominent silicate emission, whose spectral shape is sensitive to the disc temperature distribution as well as its minera…
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…
The JDISC Survey: Linking the Physics and Chemistry of Inner and Outer Protoplanetary Disk Zones
Nicole Arulanantham, Colette Salyk, Klaus Pontoppidan +20
Mid-infrared spectroscopy of protoplanetary disks provides a chemical inventory of gas within a few au, where planets are readily detected around older stars. With the JWST Disk In…
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…
C/O Ratios and the formation of wide separation exoplanets
Edwin A. Bergin, Richard A. Booth, Maria Jose Colmenares +1
The gas and solid-state C/O ratios provide context to potentially link the atmospheric composition of planets to that of the natal disk. We provide a synthesis of extant estimates…
Thermal processing of primordial pebbles in evolving protoplanetary disks
Maria Jose Colmenares, Michiel Lambrechts, Elishevah van Kooten +1
During protoplanetary disk formation, dust grains located in the outer disk retain their pristine icy composition, while solids in the inner stellar-heated disk undergo volatile lo…
High-contrast JWST-MIRI spectroscopy of planet-forming disks for the JDISC Survey
Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +26
The JWST Disk Infrared Spectral Chemistry Survey (JDISCS) aims to understand the evolution of the chemistry of inner protoplanetary disks using the Mid-InfraRed Instrument (MIRI) o…
