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 Dynamics of Infall and Accretion Shocks in the Outer Disk
Susan Terebey, Loraine Sandoval Ascencio, Lizxandra Flores-Rivera +2
High-spatial-resolution observations of disks around young stars suggest planetary systems begin forming early, during the protostellar phase (< 1 Myr) when stars accrete most of t…

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…
