exoALMA Reveals Dynamic Substructures in Planet-Forming Disks

High-resolution ALMA survey maps gas and dust in protoplanetary disks

From Arxiv Original Article

New high-resolution observations of fifteen large protoplanetary disks reveal widespread complex structures in gas and dust, indicating active planet formation processes.

Why it matters: Detailed imaging exposes physical and velocity substructures critical for understanding early planet formation dynamics.

The big picture: All but one disk show dust and gas features driven by embedded planets or large-scale instabilities.

Stunning stat: Velocity measurements achieved precision uncertainties as low as 10 meters per second across disks.

Quick takeaway: Deep, high-resolution ALMA data uncover dynamic disk environments shaped by planets, instabilities, and winds.
