摘要:

在泰拉莫、罗马和普尔科沃天文台使用AZT-24望远镜进行的近红外超新星监测计划框架内,我们在发现超新星SN 2006 jc后约36天开始,在7个月的时间内在J、H、K测光带中观测到了超新星SN 2006 jc。我们的观察证明了近红外重新变亮,在发现后约70天达到峰值,同时H-K和J-H颜色变红,直到发现后120天。在此之后,J-H似乎朝着更蓝的颜色发展。我们的数据,补充红外,光学,紫外和X射线观测发现在文献中,表明重新增亮是由周围的超新星,形成在喷出物与致密的拱星物质的相互作用热尘埃。

英文摘要:

In the framework of a program for the monitoring of Supernovae in the Near-Infrared (NIR) carried out by the Teramo, Rome and Pulkovo observatories with the AZT-24 telescope, we observed the Supernova SN2006jc in the J,H,K photometric bands during a period of 7 months, starting ~36 days after its discovery. Our observations evidence a NIR re-brightening, peaking ~70 days after discovery, along with a reddening of H-K and J-H colors until 120 days from discovery. After that date, J-H seems to evolve towards bluer colors. Our data, complemented by IR, optical, UV and X-ray observations found in the literature, show that the re-brightening is produced by hot dust surrounding the supernova, formed in the interaction of the ejecta with dense circumstellar matter.
