1A 0535+262的脉冲周期历史和相位分辨光谱
Pulse Period History and Phase Resolved Spectra of 1A 0535+262
摘要：
Be/X射线双星1A 0535+262是在1975年的一次大爆发中发现的。之后，它表现出平静期（流量低于10 mCrab），正常爆发（10 mCrab-1 Crab）和偶尔的巨大爆发（几个Crab）。结束了11年的平静，最后一次巨大的爆发发生在2005年5月/6月，但来源太靠近太阳，大多数卫星都无法观测到。随后在2005年8月发生了一次正常的爆发，这是由INTEGRAL和RXTE TOO观测到的。基于INTEGRAL数据，我们给出了源的长期脉冲周期历史，其能量依赖的脉冲轮廓和相位分辨谱的结果。
英文摘要：
The Be/X-ray binary 1A 0535+262 was discovered in 1975 during a giant outburst. Afterwards it has shown periods of quiescence (flux below 10 mCrab), normal outbursts (10 mCrab-1Crab) and occasionally giant outbursts (several Crab). Ending 11 years of quiescence, the last giant outburst took place in May/June 2005, but the source was too close to the Sun to be observed by most satellites. A subsequent normal outburst took place in August 2005, which was observed by INTEGRAL and RXTE TOO observations. Based on INTEGRAL data, we present results on the long term pulse period history of the source, on their energy dependent pulse profiles and on phase resolved spectra.
