Unraveling the Formation of Multi-Star Systems: The Significance of Gas Streamers

Multi-Star Formation

In a groundbreaking study, researchers have delved into the intricate process of multi-star system formation, shedding light on the crucial role played by gas streamers in nurturing protostars. This investigation, conducted through a combination of meticulous observations and sophisticated simulations, unveils a deeper understanding of how these celestial configurations come into being.

Multi-star systems, where stars of similar mass, like our Sun, form in close proximity to one another, are a common cosmic phenomenon. Consequently, comprehending the mechanisms behind their formation holds great significance in the broader context of star formation theories. Until recently, the complexity of these systems and the absence of high-resolution, high-sensitivity data had left astronomers grappling with uncertainty regarding the formation process. Notably, recent observations of protostars frequently revealed the existence of “streamers” — structures through which gas flows toward the developing stars. However, the origins of these streamers remained shrouded in mystery.

To unravel this celestial enigma, an international team led by Professor Jeong-Eun Lee from Seoul National University embarked on a mission utilizing the remarkable capabilities of the Atacama Large Millimeter/submillimeter Array (ALMA). Their target: the trinary protostar system IRAS 04239+2436, residing 460 light-years away in the Taurus constellation. Employing ALMA, the team detected emissions from sulfur monoxide (SO) molecules, which traced the presence of three spiral arms encircling the three protostars within the system.

In a remarkable convergence of observational data and computational simulations, led by Professor Tomoaki Matsumoto from Hosei University and powered by the supercomputers “ATERUI” and “ATERUI II” at the Center for Computational Astrophysics, National Astronomical Observatory of Japan (NAOJ), it was revealed that these three spiral arms are, in fact, the elusive streamers responsible for channeling material towards the protostars.

This synergy between observation and simulation has not only unveiled the existence of these streamers but has also provided a comprehensive understanding of how they are generated and how they contribute to the growth of the central protostars. This groundbreaking research marks a significant milestone in the study of multi-star system formation, offering valuable insights into the intricacies of celestial birth.
