Astronomers Discover a Forming Quadruple-Star System

G206.93-16.61E2 is close to the reflection nebula NGC 2023 in the Orion B molecular cloud. The Zoom-in pictures show the 1.3mm continuum emission (blue) and CO molecular outflow (orange) of ALMA observation. These observations develop an in-depth understanding of the formation of multiple star systems in the early stage.

Recently, the international team ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP) led by Prof. Liu Tie from Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences conducted a high-resolution investigation on 72 dense cores in the Orion Giant Molecular Clouds (GMCs) with the Atacama Large Millimeter/submillimeter Array (ALMA), and discovered a forming quadruple-star system within one core...
