A Comprehensive Sulfur Chemistry Network Including Excited S(1D) and SO(1Δ) for the XODIAC Photochemical Model: Accounting for Missing Sulfur Processes in Venus and Exo-Venus Analogs

Priyankush Ghosh, Namrata Rani, Jeehyun Yang +3

Sulfur chemistry plays a central role in controlling the atmospheric structure, cloud formation, and composition of Venus and Venus-like exoplanets. However, key reactions involvin…

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…

The interstellar heritage of comets

Karen Willacy, Liton Majumdar, Boncho Bonev +5

Comets have similar compositions to interstellar medium ices, suggesting at least some of their molecules maybe inherited from an earlier stage of evolution. To investigate the deg…

Water vapor as a probe of the origin of gas in debris disks

Yasuhiro Hasegawa, Riouhei Nakatani, Isabel Rebollido +5

Debris disks embrace the formation and evolution histories of planetary systems. Recent detections of gas in these disks have received considerable attention, as its origin ties up…

Chemistry in the GG Tau A Disk: Constraints from H2D+, N2H+, and DCO+ High Angular Resolution ALMA Observations

Parashmoni Kashyap, Liton Majumdar, Anne Dutrey +17

Resolved molecular line observations are essential for gaining insight into the physical and chemical structure of protoplanetary disks, particularly in cold, dense regions where p…

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 =…
