论文摘要
我们介绍了MON R1关联的窄带HALPHA和[SII]成像调查，该结果与Byurakan天文台的1 M Schmidt望远镜进行。我们的观察结果涵盖了协会中心附近的一个学位领域。这项研究的结果是发现了二十个新的Herbig-Haro结，其中一些形式是准入的流出。最扩展的是HH 1203和HH 1196，它们的长度接近一个parsec甚至更长。在寻找可能的HH物体来源的过程中，发现了几个新的含糊的恒星。列出了正在研究的MON R1区域中所有模糊的恒星对象的列表，并详细描述了最有趣的对象。来自GLIMPSE360和WISE调查的近红外数据允许找到与Mon R1有关的更多对象，其中一些具有光学对应物，以及从深层嵌入的预元素 - 序列序列对象中概述至少三个可能的H_2直接流。 MON R1的可能成员是通过其距离选择的，其降压仪和灭绝的估计。在流出源中，发现了三个嵌入式物体，其亮度大于10 L（太阳）。据估计，到MON R1复合物的平均距离为715 PC。
We present results of the narrow-band Halpha and [SII] imaging survey of Mon R1 association, performed with the 1 m Schmidt telescope of the Byurakan Observatory. Our observations covered one degree field near the center of the association. As a result of this study twenty new Herbig-Haro knots were discovered, some of which form collimated outflows. Among the most extended ones are HH 1203 and HH 1196, which have a length near one parsec or even more. In the course of search for the probable sources of HH objects several new nebulous stars were found. A list of all nebulous stellar objects in the Mon R1 area under study is presented, with the detailed description of most interesting objects. The near infrared data from the GLIMPSE360 and WISE surveys allowed to find several more objects, related to Mon R1, some of them with optical counterparts, as well as to outline at least three probable H_2 collimated flows from the deeply embedded pre-main-sequence objects. The probable members of Mon R1 were selected by their distances, their bolometric luminosities and extinctions were estimated. Among the outflow sources three embedded objects with luminosities greater than 10 L(sun) were found. The mean distance to Mon R1 complex is estimated as 715 pc.
