摘要:

我们研究的性质,39个未经证实的超新星(SNe)从斯隆数字巡天(SDSS)数据发布8(DR 8)所涵盖的天空区域,使用现有的光度和成像数据和密集的文献检索。我们确认21个对象是真正的SNe,2个是银河系的恒星,4个是可能的SNe,12个仍然未经证实的事件。提出了4个天体的可能类型:3个SN可能是Ia型,SN 1953 H可能是II型。此外,我们确定了SN 1976 N的宿主星系,并校正了SN 1958 E,1972 F和1976 N的偏移/坐标。

英文摘要:

We study the nature of 39 unconfirmed supernovae (SNe) from the sky area covered by the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8), using available photometric and imaging data and intensive literature search. We confirm that 21 objects are real SNe, 2 are Galactic stars, 4 are probable SNe, and 12 remain unconfirmed events. The probable types for 4 objects are suggested: 3 SNe are of probable type Ia, and SN 1953H is probable type II SN. In addition, we identify the host galaxy of SN 1976N and correct the offsets/coordinates of SNe 1958E, 1972F, and 1976N.
