Brandon Patel, Rosanne Di Stefano, Thomas Nelson, Francis A. Primini, Jifeng Liu, Sarah Scoles

摘要:

本文报道了在M31,r1-25中观测到的一个发光超软X射线源(SSS),它表现出向硬X射线态的光谱变化。我们记录这些光谱变化。此外,我们表明,他们有重要的影响建模的来源。源中的准软态已被观察到为SSS,这代表了一种新发现的现象。我们将展示如何证明这种状态改变器是不寻常的黑洞或中子星吸积物的例子。对这种和其他状态改变者的未来观测可以提供确定这些有趣的新来源的性质所需的信息。

英文摘要:

We report on observations of a luminous supersoft X-ray source (SSS) in M31, r1-25, that has exhibited spectral changes to harder X-ray states. We document these spectral changes. In addition, we show that they have important implications for modeling the source. Quasisoft states in a source that has been observed as an SSS represent a newly- discovered phenomenon. We show how such state changers could prove to be examples of unusual black hole or neutron star accretors. Future observations of this and other state changers can provide the information needed to determine the nature(s) of these intriguing new sources.
