[1] Detailed kinematic investigation of herbig-haro objects in the northeast region of ngc7129 / T. A. Movsessian, T. Y. Magakian, A. V. Moiseev, M. G. Gevorgian // Astrophysical Bulletin. — 2015. — Vol. 70. — P. 206–213. Using the Fabry-Perot scanning interferometer at the SAO RAS 6-m telescope, we studied a number of Herbig-Haro objects in the northeast region of NGC7129. We detected a helicoidal flow in HH234, consisting of separate high-speed knots propagating within the cavity in the interstellar medium created by the outflow. HH235 consists of at least five knots, each of which form its own bow shock front. The direction of these fronts together with the NW-SE oriented high-velocity core of the flow indicate the location of a possible source. The origin of the objects HH105 and HH821 is discussed as well. Possible Herbig-Haro outflow sources in this region are located further north of the cluster center in the vicinity of the active star V350 Cep, except for HH234 with a known source. It can be considered ascertained that the NGC7129 region consists of several star-forming cores, in which multiple outflows from stars of different masses are present. [ DOI ]
