An article published in the journal “Astronomy & Astrophysics” reports a study on the massive protostar cataloged as IRAS20126+4104 which obtained the measurement of the speed of the jets of materials that are ejected at about 100 km/h. A team of researchers led by Fabrizio Massi of the Italian National Institute of Astrophysics in Arcetri used the SOUL instrument installed on the Large Binocular Telescope (LBT) to obtain the details necessary to measure the displacements that occurred with respect to archive images dating back to 2003 and 2012. This result helps to better understand the formation processes of massive stars.
