上下文船底座的大星云是银河系中质量最大(总质量> 25000 M)的恒星形成复合体之一,包含几颗初始质量超过100 M的恒星;因此,它是研究剧烈的大质量恒星形成的物理和由此产生的反馈效应的绝佳位置,包括云分散和触发的恒星形成离子。目标。我们的目标是揭示船底座星云复合体中的冷尘埃云,确定它们的形态和质量,并研究发光的大质量恒星与这些云的相互作用。方法.我们使用APEX望远镜上的大型APEX测辐射热计照相机LABOCA,以18 00的角分辨率(在船底座星云的距离上= 0.2 pc)和一个r.m.s.,在870 m处绘制了1:25 × 1:25 ×(B 50 × 50 pc 2)的区域。噪音水平为20 mJy/梁。
Context. The Great Nebula in Carina is one of the most massive (M�; total >25 000 M�) star-forming complexes in our Galaxy and contains several stars with (initial) masses exceeding �100 M�; it is therefore a superb location in which to study the physi cs of violent massive star-formation and the resulting feedback effects, including cloud dispersal and triggered star-format ion. Aims. We aim to reveal the cold dusty clouds in the Carina Nebula complex, to determine their morphology and masses, and to study the interaction of the luminous massive stars with these clouds. Methods. We used the Large APEX Bolometer Camera LABOCA at the APEX tel escope to map a 1: 25 � � 1: 25 � (b 50� 50 pc 2 ) region at 870� m with 18 00 angular resolution (= 0.2 pc at the distance of the Carina Nebula) and an r.m.s. noise level of�20 mJy/beam.
