Soot Planets instead of Water Worlds
Jie Li, Edwin A. Bergin, Marc M. Hirschmann +3
Some low-density exoplanets are thought to be water-rich worlds that formed beyond the snow line of their protoplanetary disc, possibly accreting coequal portions of rock and water…
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 Far-Infrared Enhanced Survey Spectrometer (FIRESS) for PRIMA: Science Drivers
Klaus M. Pontoppidan, Alberto Bolatto, J D Smith +25
We present the science drivers for the Far-Infrared Enhanced Survey Spectrometer (FIRESS), one of two science instrument on the PRobe Infrared Mission for Astrophysics (PRIMA). FIR…
Cosmic cascades: How disk substructure regulates the flow of water to inner planetary systems
Sebastiaan Krijt, Andrea Banzatti, Ke Zhang +17
The influx of icy pebbles to the inner regions of protoplanetary disks constitutes a fundamental ingredient in most planet formation theories. The observational determination of th…
The JDISC Survey: Linking the Physics and Chemistry of Inner and Outer Protoplanetary Disk Zones
Nicole Arulanantham, Colette Salyk, Klaus Pontoppidan +20
Mid-infrared spectroscopy of protoplanetary disks provides a chemical inventory of gas within a few au, where planets are readily detected around older stars. With the JWST Disk In…
Emission from multiple molecular isotopologues in a high-inclination protoplanetary disk
Colette Salyk, Klaus M. Pontoppidan, Andrea Banzatti +7
We present a MIRI-MRS spectrum of the high-inclination protoplanetary disk around the solar-mass (K0) star MY Lup, obtained as part of the JWST Disk Infrared Spectral Chemistry Sur…
