A study observes a triple protostar system with spiral arms of gas that feed material to baby stars and finds a new mechanism for multiple star formation.
A team of international researchers has discovered how three baby stars are being fed by spiral arms of gas in a triple protostar system. The team, led by Professor Jeong-Eun Lee from Seoul National University, used the powerful Atacama Large Millimeter/submillimeter Array (ALMA) telescopes to observe the system called IRAS 04239+2436, located about 460 light-years away from Earth.
They found that the gas around the three protostars contains sulfur monoxide (SO) molecules, which indicates the presence of shock waves caused by the complex… More.
