A large fraction of sources in the X-ray sky are variable on time scales from sub-seconds up to decades–X-ray astronomy has thus always been “time domain astronomy”. By virtue of its survey strategy, eROSITA will provide variability information on time scales of hours up to years during the entire survey, with higher frequency visits being possible for sources at higher ecliptical latitudes. The aim of this project is to provide the scientific infrastructure for research on transient sources to be used in the projects P3, P4, and P5, in conjunction with research that is complementary to that provided in these projects.

天空中很大一部分x射线源在时间尺度上是可变的，从亚秒到几十年，因此x射线天文学一直是“时域天文学”。凭借其调查策略，eROSITA将在整个调查过程中提供从小时到年的时间尺度的变化信息，对于黄道纬度较高的源，可能会有更高的访问频率。本项目的目的是为P3、P4和P5项目中瞬态源的研究提供科学基础，并与这些项目提供的研究相辅相成。
