斯皮策c2d大型邻近星际云巡天：VII。用MIPS观察蛇夫鱼
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds: VII. Ophiuchus Observed with MIPS
摘要：
我们展示了斯皮策太空望远镜多波段成像光度计（MIPS）观测到的蛇夫座星云的14.4 deg^2图。这些高质量的地图描绘了这些云的恒星形成和非恒星形成部分内的大量点源以及扩展的尘埃排放。使用PSF拟合测光，我们检测5779源在24微米和81源在70微米在10西格玛的显着性水平。根据MIPS/2 MASS K对K $-$ [24]色星等图上的位置，与SWIRE河外巡天中24 μ m的探测结果进行了比较，确定了323个候选年轻恒星天体（YSO）。我们发现，超过一半的YSO候选人，几乎所有的原恒星I类光谱能量分布，仅限于已知的集群和聚集。
英文摘要：
We present maps of 14.4 deg^2 of the Ophiuchus dark clouds observed by the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS). These high quality maps depict both numerous point sources as well as extended dust emission within the star-forming and non-star-forming portions of these clouds. Using PSF-fitting photometry, we detect 5779 sources at 24 um and 81 sources at 70 um at the 10 sigma level of significance. Three hundred twenty-three candidate young stellar objects (YSOs) were identified according to their positions on the MIPS/2MASS K versus K$-$[24] color-magnitude diagrams as compared to 24 um detections in the SWIRE extragalactic survey. We find that more than half of the YSO candidates, and almost all the ones with protostellar Class I spectral energy distributions, are confined to the known cluster and aggregates.
