论文摘要
我们介绍了位于L1287 Cloud中的近距离RNO 1B和1C（6 $''$ shita）的新X射线观测。 RNO 1B于1978年至1990年爆发，被归类为Fu Orionis Star（FUOR）。 RNO 1C还显示了FUOR的大部分特性，但尚未看到喷发。仅知道几十个燃料，并且很少有两个具有小角度分离的物体的存在，这表明是共同的起源。 Chandra淡淡地检测到了这两颗恒星，我们在其他先前检测到的燃料的框架内总结了它们的X射线特性。我们还报告了L1287中的其他X射线检测，其中包括深膜的年轻恒星RNO 1G，类似喷气式的无线电源VLA 3和一个神秘的硬弹性源，没有2个弹药，仅在两次Chandra曝光中被检测到2个弹药。
We present new Chandra X-ray observations of the close pair of young stars RNO 1B and 1C (6$''$ separation) located in the L1287 cloud. RNO 1B erupted in 1978 - 1990 and is classified as an FU Orionis star (FUor). RNO 1C also shows most of the properties of an FUor but no eruption has yet been seen. Only a few dozen FUors are known and the presence of two such objects with a small angular separation is rare, suggesting a common origin. Both stars were faintly detected by Chandra and we summarize their X-ray properties within the framework of other previously detected FUors. We also report other X-ray detections in L1287 including the deeply-embedded young star RNO 1G, the jet-like radio source VLA 3, and an enigmatic hard flaring source with no 2MASS counterpart that was only detected in the second of two Chandra exposures.
