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…

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…

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…

The Carbon Isotopic Ratio and Planet Formation

Edwin A. Bergin, Arthur Bosman, Richard Teague +6

We present the first detection of 13CCH in a protoplanetary disk (TW Hya). Using observations of C2H we measure CCH/13CCH = 65 +/- 20 in gas with a CO isotopic ratio of 12CO/13CO =…

Molecular Gas Tracers in Young and Old Protoplanetary Disks

Dana E. Anderson, L. Ilsedore Cleeves, Geoffrey A. Blake +6

Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to accurately derive disk properties, we need a thorough und…
