Companion IR detection limits in young associations

The frequency and properties of multiple star systems offer powerful tests of star formation models. Multiplicity surveys over the past decade have shown that binary properties...多星系统（multiple star systems）的出现频率与物理特性，可为恒星形成模型提供强有力的检验依据。过去十年间开展的恒星多重性巡天（multiplicity surveys）研究表明，双星（binary）的物理特性……
