Overview

• High-resolution observations of G336.018-00.827 reveal at least two streamers linking the molecular cloud core to the protostar’s vicinity.
• One streamer shows a velocity gradient consistent with rotation and possible infall, supporting active mass delivery.
• Researchers did not detect the anticipated several-hundred–astronomical-unit dust disk, suggesting no disk or an extremely small one at the observed scales.
• The structures operate on scales larger than 1,000 astronomical units and can transport substantial gas despite stellar winds and radiation.
• The findings, published August 20 in Science Advances (DOI: 10.1126/sciadv.adw4512), precede planned ALMA surveys to assess prevalence and to probe closer to confirm or rule out small disks.
