Ein internationales Forscherteam um Dr. Alessio Caratti o Garatti vom Dublin Institute for Advanced Studies (Irland) hat erstmals beobachtet, wie ein massereicher junger Stern durch den Einfall von Materie wächst. Dabei waren die Daten des abbildenden Ferninfrarot- Spektrometers FIFI-LS der Universität Stuttgart an Bord der fliegenden Infrarotsternwarte SOFIA von entscheidender Bedeutung. Die Arbeit wurde in dem Fachjournal Nature Physics veröffentlicht.*
Die Astronomen haben den Stern S255IR NIRS 3 (Kurzform: NIRS 3), der 20-mal schwerer ist als unsere Sonne, mit SOFIA - dem Stratosphären Observatorium für Infrarot Astronomie - während dieses Wachstums beobachtet und diese Informationen mit Bildern und Spektren anderer Mvxstthmsd-Egouihpdbeewq (Veqizs Hsfmrdgrcsj, GMR/KLH, Divkh Gtuj Tezgldfryxv, QSM/HHF) xkfmglukvr.
