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.

Mon R1 关联中的新 Herbig-Haro 对象和流出

我们展示了使用 Byurakan 天文台的 1 m 施密特望远镜进行的 Mon R1 协会的窄带 Halpha 和 [SII] 成像调查的结果。我们的观察涵盖了协会中心附近的 1 度场。这项研究的结果是发现了 20 个新的 Herbig-Haro 结，其中一些形成了准直的流出物。其中扩展最多的是 HH 1203 和 HH 1196，它们的长度接近 1 秒差距甚至更长。在寻找 HH 天体的可能来源的过程中，发现了几颗新的星云。列出了所研究的 Mon R1 区域的所有星云，并详细描述了最有趣的天体。来自 GLIMPSE360 和 WISE 调查的近红外数据允许发现更多与 Mon R1 相关的物体，其中一些具有光学对应物，以及从深度嵌入的前主序列对象中勾勒出至少三个可能的 H_2 准直流。Mon R1 的可能成员是根据距离选择的，并估计了它们的热光度和消光度。在流出源中发现了三个光度大于 10 L（太阳）的嵌入物体。到 Mon R1 复合体的平均距离估计为 715 pc。
