CAHA Observing Run for NIR Photometry of Young Stellar Objects in SNR Shock Wave Interaction

恒星诞生于稠密的星际分子云。如果超新星爆炸发生在新形成的星星附近，超新星遗迹将改变原星星周围的分子云、包层和吸积盘的物理性质。此外，形成星星及其行星的物质将富含超新星前身星星内部和超新星爆炸本身产生的化学元素。在我们太阳系的测量表明，它一定也被附近的超新星富集了。我们将使用卡拉阿尔托天文台（CAHA）的2.2米望远镜对被认为与分子云相互作用的超新星遗迹进行近红外测光。根据新的数据，我们将确定超新星遗迹内部或附近的年轻恒星物体。这些年轻的恒星天体将在未来的高分辨率观测中得到更详细的研究。

Stars are born out of dense interstellar molecular clouds. If a supernova explosion occurs near a newly forming star, the supernova remnant will change the physical properties of the molecular cloud, the envelope, and the accretion disk around the proto star. In addition, the matter out of which the star and its planets form will be enriched with chemical elements that were produced inside the progenitor star of the supernova and in the supernova explosion itself. Measurements in our Solar system show that it must have also been enriched by a nearby supernova. We will carry out near-infrared photometry of supernova remnant which are believed to be interacting with molecular clouds using the 2.2m telescope of the Calar Alto Observatory (CAHA). Based on the new data we will identify young stellar objects inside or in the very vicinity of supernova remnants. These young stellar objects will be studied in more detail in dedicated future observations with higher resolution.
