摘要:

在长期宁静期后,低质量X射线双星可能因吸积盘内的不稳定性而表现出强烈的X射线爆发。这些爆发有时可以在光学波长下先于X射线被检测到,作为早期预警,有助于深入研究吸积盘性质,基于光学和X射线上升之间的延迟。我们探索 Vera C. Rubin 天文台的遗产空间与时间调查(LSST)通过光学观测早期检测这些爆发的潜力。我们基于目前计划的调查频率、滤光片特定深度和其他影响早期检测的因素评估LSST的能力。我们开发并应用了一个扩展的指标来评估爆发的可检测性和恢复率。我们发现,尽管存在早期检测XRB爆发的固有潜力,目前计划的调查策略使早期XRB爆发的检测变得具有挑战性。最后,我们展示了如何利用这一估计来推断随着LSST推进而银河系中更广泛的LMXB人口。

英文摘要:

Following long periods of quiescence, low-mass X-ray binaries can exhibit intense X-ray outbursts triggered by instabilities within the accretion disk. These outbursts can sometimes be detected in optical wavelengths before being detected in X-rays, acting as an early onset warning and enabling a deep study of accretion disk properties informed by the lag between optical and X-ray rise. We explore the potential of Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) to detect these outbursts early through optical observations. We evaluate the capabilities of LSST based on currently planned survey cadence, filter-specific depth, and other observational factors that affect early detection. We develop and apply an extended metric to assess outburst detectability and recovery fraction. We find that despite inherent potential for early detection of XRB outbursts, the currently planned survey strategy makes it challenging to detect early onset of XRBs. Lastly, we demonstrate how this estimate can be used to infer the wider LMXB population in the Galaxy as the LSST progresses.
