Artist’s impression of the triple protostars, IRAS 04239+2436. New research utilizing both observations and simulations has shed light on the formation of multi-star systems. Credit: ALMA (ESO/NAOJ/NRAO)Researchers using ALMA and advanced simulations have clarified the formation of multi-star systems, identifying and explaining the role of “streamers” feeding developing protostars.New observations and simulations of three spiral arms of gas-feeding material to three protostars forming in a trinary system have clarified…

Dark matter fluctuations in the lens system MG J0414+0534. The whitish blue color represents the gravitationally lensed images observed by ALMA. The calculated distribution of dark matter is shown in orange; brighter regions indicate higher concentrations of dark matter and dark orange regions indicate lower concentrations. Credit: ALMA(ESO/NAOJ/NRAO), K. T. Inoue et al.A team of researchers has used the gravitational lensing of the MG J0414+0534 system, observed with ALMA, to map dark matter distribution in unprecedented…
