We present the first detection of ^13 CCH in a protoplanetary disk (TW Hya). Using observations of C _2 H, we measure CCH/ ^13 CCH = 65 ± 20 gas with a CO isotopic ratio of ^12 CO/ ^13 CO = 21 ± 5. The TW Hya disk exhibits a gas phase C/O that exce

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) on the James Webb Space Telescope (JWST). With a growing sample of >30

Mid-infrared spectroscopy is one of the few ways to observe the composition of the terrestial planet forming zone, the inner few au, of proto-planetary disks. The species currently detected in the disk atmosphere, for example CO, CO2, H2O and C2H2, a

Molecular D/H ratios are frequently used to probe the chemical past of Solar System volatiles. Yet it is unclear which parts of the Solar Nebula hosted an active deuterium fractionation chemistry. To address this question, we present 0".2-0".4 ALMA o
