Astronomers Found Spirals Inside a Dust Gap of a Young Star Forming Disk

lanets form within disks composed of dust grains and gas. Planets can gather dust grains from their orbits, resulting in dust gaps or cavities, and can also cause spiral waves within the parental disks based on theoretical predictions. To understand where and when planets can form at early stages, ALMA’s capability of seeing disk material with high resolution can depict smoking-gun evidence of infant planets hidden in disks…
