摘要

我们分析了xmm -牛顿卫星观测中发现的5个未知x射线源的x射线光谱和光曲线。对于两个物体，我们发现了x射线耀斑。另外三个天体的x射线光谱与神秘的 Cas类似物相似，可能是这类恒星的新候选者。所有考虑的光源在DSS光学图像中都隐约可见。我们认为，所有被研究的物体要么是非常遥远的恒星，要么是瞬态源。多方面的

A study of unknown X-ray sources

We analyze the X-ray spectra and light curves of five unknown X-ray sources found in the observations obtained by the XMM-Newton satellite. For two objects we have found X-ray flares. Three other objects have X-ray spectra similar to those of enigmatic 𝛾 Cas analogs and may be new candidates for such stars. All the considered sources are faintly visible in the DSS optical images. We suggest that all the studied objects can be either very distant stars or transient sources. Multifaceted
