Scientists used supercomputers to simulate how stars form in groups. They found that magnetic fields help bring protostars together to create binary star systems.

Stars are born inside giant clouds of gas and dust in space. As these clouds collapse, they create dense regions where new stars start to take shape. Sometimes, two newborn stars become gravitationally bound, forming a binary star system. Researchers have long wondered how this happens so quickly.

To investigate, scientists ran advanced simulations using supercomputers like the National Astronomical Observatory of Japan's ATERUI III system. The results showed that magnetic fields threading through surrounding gas can help draw protostars closer together. This process removes angular momentum from the pair, allowing them to spiral inward and form a binary system within a realistic timescale.

The simulations also highlighted the importance of magnetic fields in this process. Without them, the protostars would move farther apart instead of closer together.

Why It Matters

Understanding how stars form can help us better understand the universe and its mysteries. This discovery could also shed light on how massive black holes merge, which is important for understanding galaxy evolution.
