Near infrared view on PDRs

We performed photometric observations of the S255, S257, S140, NGC7358 and the Orion Bar photo-dissociation regions (PDRs) at 2 micron using narrow-band filters centered on the...本研究使用中心波长为[原文未完整提供]的窄带滤光片，在2微米波段对S255、S257、S140、NGC7358以及猎户座棒光解离区域（photo-dissociation regions，PDRs）开展了测光观测。
