摘要：
We report on the detection of a thermal disc component from the stellar-mass black hole binary XTE J1118+480 in the canonical low/hard state. The presence of a thermal component with a temperature of approximately 0.21 keV in the Chandra spectra of XTE J1118+480 is found at more than the 14 sigma confidence level. Based on this evidence, we argue that the accretion disc in XTE J1118+480 is not truncated far from the central black hole in contrast with previous claims.
