The 3rd paper details some of the most interesting findings that Webb made. Specifically, the paper focuses on a protoplanetary disk around the young star HL Tauri, or HL Tau, 457 light-years away. Like most protoplanetary disks in young planetary systems, this one has multiple rings of material in the disk.
Scientists first saw those rings using the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope in the Atacama Desert, Chile. And the gaps between the rings are where new planets might be developing.
Additionally, Webb observed the protoplanetary disk systems SAO 206462 and MWC 758, as discussed in the other two papers.
SAO 206462 是一顆擁有星周盤的年輕恆星，並且其星周盤內有明顯的螺旋臂結構。該恆星距離地球約400光年，在天球上位於豺狼座
