报道了红外K波段月掩星搜索前主序星双星的进展。从1986年秋天到1989年秋天，观测到了13个天体，都在金牛座恒星形成区。新发现的五颗双星是：DF Tau、DI Tau、FS Tau（哈洛6-5）A、FV Tau（哈洛6-8）和FW Tau，它们的预测距离从0.01到0.57弧秒不等。包括以前报道的结果在内，共观测到31个天体，其中金牛座21个，蛇夫座10个，共发现9个双星系统，观测到的双星频率（0.29）与太阳型主序星的频率一致。
The progress of an infrared K band lunar occultation search for binaries among premain-sequence stars is reported. From the fall of 1986 to the fall of 1989, 13 objects have been observed, all in the Taurus star-forming region. Five new binaries have been discovered: DF Tau, DI Tau, FS Tau (Haro 6-5) A, FV Tau (Haro 6-8), and FW Tau, with projected separations ranging from 0.01 to 0.57 arcsec. Including results reported previously, a total of 31 objects, 21 in Taurus and 10 in Ophiuchus, have been surveyed and nine double systems have been found. The detected binary frequency (0.29) seems consistent with that of the solar-type main-sequence field stars.
