We intend to perform spectroscopy of a subsample of the stellarpopulation embedded in two isolated star-forming globules (DR18 andECX6-21) in the Cygnus X region. For that, we were awared 3 observingnights with the CAFOS instrument on Calar Alto. The globules to bestudied were probably formed as a consequence of the erosion of thatmolecular complex by the energetic input of the luminous stellarassociation Cygnus OB2 and we want to test the 'triggeredstar-formation' scenario. The proposed observations are based onsuccessfull PANIC observations at Calar Alto from last year inaddition to a data obtained through a dedicated program that usesHerschel, SOFIA (Stratospheric Observatory for Infrared astronomy),and millimeter molecular line mapping. The observations with CalarAlto continue our study of several star-forming globules in Cygnus X(Schneider et al. 2016) and one particular in Cygnus X(IRAS20319+3958, Djupvik, Comeron, Schneider 2017).

我们打算对天鹅座X区域两个孤立的恒星形成球（DR 18和ECX 6 -21）中的恒星群子样本进行光谱分析。为此，我们在卡拉尔阿尔托用CAFOS仪器观察了3个晚上。要研究的球状体可能是由于明亮的恒星协会天鹅座OB 2的能量输入对该分子复合体的侵蚀而形成的，我们想测试“触发恒星形成”的情景。 拟议的观测是基于去年在Calar Alto成功的PANIC观测，以及通过使用Herschel，索菲亚（平流层红外天文台）和毫米分子线测绘的专用程序获得的数据。CalarAlto的观测继续了我们对天鹅座X中几个恒星形成球状体的研究（Schneider et al. 2016），以及天鹅座X中一个特殊的球状体（IRAS 20319 +3958，Djupvik，Comeron，Schneider 2017）。
