What's Happening?
A team of researchers from Kyoto University and the University of Tokyo has discovered that massive stars are fed by cosmic highways, or streamers, which are flows of gas that bring matter from scales larger than a thousand astronomical units. This finding challenges the previous understanding that accretion disks were the primary method of feeding young stars. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, the researchers observed a young star being fed by two streamers, one of which was connected to the central region of the star. This suggests that streamers can transport large amounts of gas to feed star-forming regions, even in the presence of feedback from the central star.

Why It's Important?
The discovery of cosmic highways feeding massive stars provides new insights into the process of star formation, particularly for high-mass stars. Understanding how these stars accumulate mass so quickly is crucial for comprehending the dynamics of the universe and the formation of celestial bodies. This research could lead to a reevaluation of existing models of star formation and contribute to a deeper understanding of the mechanisms that govern the universe. The findings also highlight the importance of advanced observational tools like ALMA in uncovering previously unseen cosmic phenomena.
What's Next?
The research team plans to expand their study by observing other regions to determine if this mode of accretion is common in the formation of massive stars. They also aim to explore the gas close to the star to confirm or rule out the presence of small disks. These future studies could further elucidate the role of streamers in star formation and potentially lead to new models that better explain the accumulation of mass in high-mass stars.
