How Stellar Winds Fuel Sagittarius A*
from Bedtime Astronomy Hosted by Synthetic Universe
Astronomers have traced mysterious gas clouds near the center of the Milky Way back to an unexpected origin: the binary star system IRS 16SW. These clouds, part of the so-called G-cloud streamer, follow nearly identical trajectories—strong evidence they share a common source. Simulations reveal that colliding stellar winds from the binary compress gas into dense clumps, which gradually drift inward toward Sagittarius A*. The result is a direct link between massive stars and black hole feeding, offering new insight into how matter is recycled in one of the most extreme environments in the galaxy.
