Ammonium salt formation and abundance in protoplanetary disks

Maxime Ruaud, Jean-Christophe Loison, Uma Gorti

Ammonium salts may represent an important reservoir of volatile species in Solar system primitive bodies, but the question of how and when these salts can form during the star form…

JWST/MIRI Reveals the Evolution from Molecular to Atomic Disk Winds

Naman S. Bajaj, Ilaria Pascucci, Sylvie Cabrit +10

The evolution and dispersal of protoplanetary disks--governed by accretion, magnetically launched jets and winds, and photoevaporative winds--fundamentally shape planetary systems.…

Project Hephaistos -- IV. James Webb Space Telescope Observations of Two Dyson Sphere Candidates

Erik Zackrisson, Arjan Bik, Anita Ali Asgar +11

We report on JWST/MIRI imaging and spectroscopy of two M-dwarf stars previously singled out by project Hephaistos as potential Dyson-sphere candidates (their candidates D and E) du…

From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius

Chengyan Xie, Ilaria Pascucci, Feng Long +23

We present JWST/MIRI spectroscopy of 14 disks in the older (~5-10 Myr) Upper Scorpius (USco) association and use slab of gas in local thermal equilibrium to infer basic gas propert…

Edge-On Disk Study (EODS) II: HCO and CO vertical stratification in the disk surrounding SSTTau042021

C. Foucher, A. Dutrey, V. Piétu +17

Context. Edge-on disks offer a unique opportunity to directly examine their vertical structure, providing valuable insights into planet formation processes. We investigate the dust…

Edge-On Disk Study (EODS) III: Molecular Stratification in the Flying Saucer Disk

A. Dutrey, O. Denis-Alpizar, S. Guilloteau +22

Context: Investigating the vertical distribution of molecular content in protoplanetary disks remains difficult in most disks mildly inclined along the line of sight. In contrast,…
