Velocity and line-width residuals derived from discminer models applied to synthetic observations of planet-disc interaction (q = 2 × 10−3 , ϕp = −45◦ ) and disc instabilities. Details of the simulation setups are provided in Sect. 3.1. All discs are inclined by −30◦ , and the residuals from all mechanisms are shown on the same color scale indicated on the left. Semi red-blue circles in the bottom left corners of the top-row panels indicate the locations of the redshifted and blueshifted sides of the simulated disc, which are useful to understand the velocity structure of the non-Keplerian flows -- astro-ph.EP

exoALMA XX: Tomographic Detection of Embedded Planets in Protoplanetary Disks

by Keith CowingMarch 16, 2026March 16, 2026

The exoALMA Large Program has revealed a wealth of substructures in the dust and molecular line emission of several protoplanetary discs, suggesting that planet formation may unfold within highly dynamic […]

The image to the left, taken with ESO’s Very Large Telescope (VLT), shows a possible planet being born around the young star HD 135344B.

A Newborn Planet Observed Sculpting The Dust Around It

by Keith CowingJuly 21, 2025

Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star.
