摘要: We present a Chandra/Advanced CCD Imaging Spectrometer I-array observation of GRO J1744-28. detected source at position R.A. = 17h44m3309, decl. -28°44'270 (J2000.0; with 1 σ error ~08), consistent both ROSAT and interplanetary network localizations J1744-28 when it was in outburst. This makes likely that we have the quiescent X-ray counterpart Our Chandra demonstrates previously proposed infrared is not related to The 0.5-10 keV luminosity (2-4) × 1033 ergs s-1 (assuming near Galactic center distance 8 kpc). discuss our results context emission pulsating nonpulsating neutron star transients.
