ANALYSIS OF A STATE CHANGING SUPERSOFT X-RAY SOURCE IN M31
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 …
