摘要珀斯自动超新星搜索使用西澳大利亚珀斯天文台的61厘米PLAT(珀斯洛厄尔自动望远镜)。自1993年1月1日以来,已经有5颗超新星被发现。对前三年数据的分析进行了讨论,并提出了初步结果。我们发现Ib/c型的速率为0.43 ± 0.43 SNu,IIP型的速率为0.86 ± 0.49 SNu,其中SNu是“超新星单位”,以每世纪每1010 LB星系的超新星数表示。这些值是哈勃常数为75 kms−1 Mpc−1,标度为(H 0/75)2。
Abstract The Perth Automated Supernova Search uses the 61-cm PLAT (Perth Lowell Automated Telescope) at Perth Observatory, Western Australia. Since 1993 January 1, five confirmed supernovae have been found by the search. The analysis of the first three years of data is discussed, and preliminary results presented. We find a Type Ib/c rate of 0·43±0·43 SNu, and a Type IIP rate of 0·86±0·49 SNu, where SNu are ‘supernova units’, expressed in supernovae per 1010 LB ⊙ galaxy per century. These values are for a Hubble constant of 75 kms−1 Mpc−1, and scale as (H 0/75)2.
