标题： Completing the puzzle of the 2004-2005 outburst in V0332+53: the brightening phase included

摘要： 展示了利用 RXTE 观测台在 2004-2005 年 X 射线脉冲星 V0332+53 强烈爆发期间获得的数据分析结果。 首次详细分析了覆盖爆发增强阶段的观测数据。 源参数及其在增强和衰减阶段演化过程中的比较未显示出任何滞后行为的证据。 研究发现，增强和衰减阶段能量与回旋吸收线的能量依赖关系几乎相同。 完整的数据序列（包括爆发增强和衰减阶段）使得对源磁场施加更严格的限制成为可能。 脉冲轮廓和脉动分数被研究为光度和光子能量的函数。 显示英文摘要

摘要： Analysis of the data obtained with the RXTE observatory during a powerful outburst of the X-ray pulsar V0332+53 in 2004-2005 is presented. Observational data covering the outburst brightening phase are analysed in detail for the first time. A comparison of source parameters and their evolution during the brightening and fading phases shows no evidence for any hysteresis behaviour. It is found that the dependences of the energy of the cyclotron absorption line on the luminosity during the brightening and fading phases are almost identical. The complete data sequence including the outburst brightening and fading phases makes it possible to impose the more stringent constraints on the magnetic field in the source. The pulse profile and pulsed fraction are studied as functions of the luminosity and photon energy.
