摘要:

Einstein@Home汇集了来自192个国家的数十万志愿者的计算机能力,以“挖掘”大型数据集。它现在已经在2007年2月从阿雷西博天文台拍摄的无线电测量数据中发现了一颗40.8 Hz的孤立脉冲星。额外的定时观测表明,这颗脉冲星可能是一颗被破坏的再循环脉冲星。PSR J2007+2722的脉冲轮廓非常宽,几乎在整个自旋周期内都有发射;脉冲星可能具有紧密对齐的磁轴和自旋轴。志愿者提供的巨大计算能力应该能够实现更多这样的发现。

英文摘要:

Einstein@Home aggregates the computer power of hundreds of thousands of volunteers from 192 countries to "mine" large data sets. It has now found a 40.8 Hz isolated pulsar in radio survey data from the Arecibo Observatory taken in February 2007. Additional timing observations indicate that this pulsar is likely a disrupted recycled pulsar. PSR J2007+2722's pulse profile is remarkably wide with emission over almost the entire spin period; the pulsar likely has closely aligned magnetic and spin axes. The massive computing power provided by volunteers should enable many more such discoveries.
