摘要：
Two previously unknown X-ray sources in the globular clusters Ter 6 and NGC 6652 have been detected by ROSAT, during the sky survey. The source in Ter 6 has a luminosity between 0.5 and 2.0 keV of approximately 2.9 x 10(36) erg s-1. The source in NGC 6652 has a luminosity approximately 7.6 x 10(35) erg s-1. Both sources are brighter than previous detection limits. These discoveries add two to the small number of known bright X-ray sources in globular clusters. The presence of bright X-ray sources in Ter 6 and NGC 6652 is compatible with the idea that such sources are formed via 2-body tidal capture.
