Accretion Burst Crystallizes Silicates in a Planet-Forming Disk
Jeong-Eun Lee, Chul-Hwan Kim, Jaeyeong Kim +13
The paper reports JWST mid‑infrared observations of the bursting protostar EC 53 that reveal crystalline silicate emission appearing only during an accretion burst, providing direc…
Setting the Stage: The Early History of the Solar System
Antgona Segura, Rachel L. Smith, Myriam Telus +3
The paper reviews how the early solar system formed and how key organic molecules arose, using evidence from meteorites and observations of protoplanetary disks.
JWST/MIRI Detection of Molecular H Winds from an Edge-on Class II Source HV Tau C
Vinod Chandra Pathak, P. Manoj, Himanshu Tyagi +14
The paper uses JWST/MIRI mid‑infrared spectroscopy to detect and characterize a wide‑angled molecular hydrogen wind from the edge‑on Class II protoplanetary disk HV Tau C, measurin…
Dust masses of Upper Scorpius disks and their statistics
Huiyi Deng, Yao Liu, Min Fang
The paper measures dust masses of 136 protoplanetary disks in Upper Scorpius using ALMA 0.88 mm observations and a new grid of radiative‑transfer models, finding dust masses about…
GRACE-DG: A Discontinuous Galerkin Method-Based Code for General Nonlinear Coagulation-Fragmentation Equations
Jing Yang, Zhuo Chen, Xue-Ning Bai
The paper presents GRACE-DG, an open‑source high‑order discontinuous Galerkin code that solves non‑linear coagulation‑fragmentation equations for dust evolution in protoplanetary d…
Probing Planet Formation with JWST Spectroscopy of IC348: Sustained Diversity but Limited Chemical Evolution and Pebble Drift
John S. Carr, Joan R. Najita
JWST/MIRI spectroscopy of T Tauri disks in the IC 348 cluster shows a wide range of molecular ratios but little change in the inner disk C/O ratio between 1–5 Myr, indicating limit…
