摘要:

我们报告发现的爆发振荡从间歇性吸积动力毫秒脉冲星(AMP)HETE J1900.1-2455,与频率约1赫兹低于已知的自旋频率。突发振荡性质与非AMP和Aql X-1(具有低得多的占空比的间歇性AMP)的突发振荡性质比AMP SAX J1808.4-3658和XTE J1814-338的突发振荡性质更相似。我们讨论了模型的突发振荡和不稳定机制的影响。

英文摘要:

We report the discovery of burst oscillations from the intermittent accretion-powered millisecond pulsar (AMP) HETE J1900.1-2455, with a frequency approximately 1 Hz below the known spin frequency. The burst oscillation properties are far more similar to those of the non-AMPs and Aql X-1 (an intermittent AMP with a far lower duty cycle), than those of the AMPs SAX J1808.4-3658 and XTE J1814-338. We discuss the implications for models of the burst oscillation and intermittency mechanisms.
