Core Viewpoint - A multinational team, including researchers from Nanjing University, has confirmed the detection of phosphine on an exoplanet, Wolf 1130C, which may enhance the understanding of the chemical environment in the universe [1][3]. Group 1: Research Findings - The research results were published in the journal "Science," and the study is considered a milestone in the field [1]. - Phosphine has previously been detected in the atmospheres of Jupiter and Saturn, but its presence on brown dwarfs was not confirmed until now [1][3]. - The study indicates that approximately 1 in every 10 million molecules in the atmosphere of Wolf 1130C is phosphine [3]. Group 2: Theoretical Implications - Two hypotheses were proposed regarding the presence of phosphine: one suggests that phosphorus is bound in phosphorus trioxide, and Wolf 1130C lacks sufficient oxygen for phosphine formation; the other posits that phosphine may originate from the neighboring stars [3][5]. - The international team is planning new observations to search for phosphine in other brown dwarfs to further validate their theoretical assumptions [5].
