Molecules in the shadows of the protoplanetary disk HD 143006: Evidence for C/O from simultaneously modeling fourteen ALMA lines
S. E. van Terwisga, P. Woitke, A. M. Weiss +2
The inner disk of the T Tauri star HD 143006 is inclined and casts a broad shadow on a large portion of the outer disk. We use this extraordinary geometry to study the impact of st…
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 =…
A potential site for wide-orbit giant planet formation in the IM Lup disk
Arthur Bosman, Johan Appelgren, Edwin A. Bergin +2
The radial transport, or drift, of dust has taken a critical role in giant planet formation theory. However, it has been challenging to identify dust drift pile ups in the hard-to-…
UV-driven Chemistry as a Signpost for Late-stage Planet Formation
Jenny K. Calahan, Edwin A. Bergin, Arthur D. Bosman +14
The chemical reservoir within protoplanetary disks has a direct impact on planetary compositions and the potential for life. A long-lived carbon-and nitrogen-rich chemistry at cold…
The kinematics and excitation of infrared water vapor emission from planet-forming disks: results from spectrally-resolved surveys and guidelines for JWST spectra
Andrea Banzatti, Klaus M. Pontoppidan, José Pérez Chávez +19
This work presents ground-based spectrally-resolved water emission at R = 30000-100000 over infrared wavelengths covered by JWST (2.9-12.8 m). Two new surveys with iSHELL and VI…
Water shielding in the terrestrial planet-forming zone: Implication for inner disk organics
Sara E. Duval, Arthur D. Bosman, Edwin A. Bergin
The chemical composition of the inner region of protoplanetary disks can trace the composition of planetary building material. The exact elemental composition of the inner disk has…
