New observations and simulations have make clear the formation of multi-star techniques by revealing the method of fuel streamers feeding materials to a few protostars in a trinary system.

Understanding the formation of multi-star techniques is essential for creating a complete principle of star formation, as most stars related in mass to the solar are a part of multi-star techniques. Nevertheless, the complexity and lack of high-resolution, high-sensitivity knowledge have left astronomers unsure concerning the particular formation situation.

In current observations of protostars, constructions known as “streamers” of fuel flows in direction of the protostars have been generally noticed, however the formation mechanism behind these streamers has remained unclear.

A group led by Professor Jeong-Eun Lee from Seoul Nationwide College used the Atacama Giant Millimeter/submillimeter Array (ALMA) to watch the trinary protostar system IRAS 04239+2436, situated 460 light-years away within the Taurus constellation. The group found that emissions from sulfur monoxide (SO) molecules hint three spiral arms across the three protostars forming within the system. Their findings have been revealed in The Astrophysical Journal.

Comparisons with simulations performed by Professor Tomoaki Matsumoto from Hosei College utilizing the supercomputers ATERUI and ATERUI II on the Heart for Computational Astrophysics on the Nationwide Astronomical Observatory of Japan (NAOJ) have revealed that the three spiral arms are the streamers feeding materials to the three protostars.

By a mix of observations and simulations, this research has supplied the primary perception into the creation of streamers and their contribution to the expansion of the protostars on the heart.
