Around the water snowline: I. Effects of dynamical and chemical interplay on mid-infrared water spectra of protoplanetary discs

Till Kaeufer, Sebastiaan Krijt, Edwin A. Bergin +2

Protoplanetary discs' infrared water spectra (e.g. as observed by JWST) encode information about the underlying water distribution and physical conditions. In this work, we examine…

The ALMA View of the Edge-on Gomez's Hamburger System: A Highly-Dynamic, Asymmetric Protoplanetary Disk Reveals the Earliest Phases of Giant Planet Formation

Charles J. Law, Jensen Lawrence, Richard Teague +18

Chemical tracers provide some of the strongest observational signatures of ongoing planet formation and localized dynamical perturbations in protoplanetary disks. In particular, su…

Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments

Aashish Gupta, Cristiano Longarini, L. Ilsedore Cleeves +5

Context. A significant fraction (>30%) of planet-forming disks and planetary are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism resp…

Chemical Divergence and Water Depletion: Gas Properties of Evolved Upper Scorpius Disks Revealed by JWST/MIRI

Eshan Raul, Ke Zhang, Abygail Waggoner +25

Tracing the chemical evolution of protoplanetary disks over time requires observations of disks at different ages. However, most JWST/MIRI surveys published to date have targeted y…

JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation

María José Colmenares, Edwin A. Bergin, Ke Zhang +27

We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum (1 Myr old) source, to investigate the chemical composition and dynamical origin of i…

A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions

Yiting Li, Michael R. Meyer, Skylar D'Angiolillo +29

At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial plane…
