M 67 Chandra X-Ray Point Source Catalog

Metadata Updated: April 10, 2026

The M 67 Chandra X-Ray Point Source Catalog contains the results of a 47 ks Chandra/ACIS observation of the old (4 Gyr) open cluster M67. The authors detected 25 proper-motion cluster members (including ten new sources) and 12 sources (all new) that they suspect to be M 67 members from their locations close to the main sequence (1 < B-V < 1.7). Of the detected members, 23 are binaries. In addition to cluster members, about 100 background sources were detected, many of which were identified with faint objects in the ESO Imaging Survey (EIS, Momany et al. 2001, A&A, 379, 436). This table summarizes the X-ray properties of the 158 sources which were detected by Chandra in this observation, and also lists the ROSAT (Belloni et al., 1998A&A...335..517B) and optical (candidate) counterparts. This table was created by the HEASARC in January 2007 based on CDS table J/A+A/418/509/table1.dat This is a service provided by NASA HEASARC .
