"Discovery: Astronomers Spot a Rare Quadruple-Star System in the Making"

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a young quadruple-star system within a star-forming region in the Orion constellation. The system consists of two protostars and two gas concentrations that are likely to undergo gravitational collapse in the future. The observations provide insights into the formation mechanisms of multiple-star systems and reveal intricate gas outflows caused by stellar winds. The discovery highlights the complex interactions among members in a forming higher-order star system and raises questions about the role of elongated ribbon-like structures in gas accretion and star formation.
