A Soft X-ray Transient in the M31 Bulge
Benjamin F. Williams, Michael R. Garcia, Jeffrey E. McClintock +2
We have examined a probable soft X-ray transient source in the M31 bulge at R.A.=0:42:41.814 +/- 0.08", Dec. = 41:16:35.86 +/- 0.07". On the three occasions we observed the source,…
Chandra and Hubble Study of a New Transient X-ray Source in M31
Benjamin F. Williams, Michael R. Garcia, Jeffrey E. McClintock +2
We present X-ray and optical observations of a new transient X-ray source in M31 first detected 23-May-2004 at R.A.=00:43:09.940 +/- 0.65'', Dec.=41:23:32.49 +/- 0.66''. The X-ray…
A Potential Supernova Remnant/X-ray Binary Association in M31
Benjamin F. Williams, Robin Barnard, Michael R. Garcia +3
The well-studied X-ray/Optical/Radio supernova remnant DDB 1-15 (CXOM31 J004327.8+411829; r3-63) in M31 has been investigated with archival XMM-Newton and Chandra observations. The…
Optical Constraints on an X-ray Transient Source in M31
Benjamin F. Williams, Michael R. Garcia, Frank A. Primini +2
We have detected a transient X-ray source in the M31 bulge through a continuing monitoring campaign with the Chandra ACIS-I camera. The source was detected at R.A.=00:42:33.428 +/-…
An X-ray Transient and Optical Counterpart in the M31 Bulge
Benjamin F. Williams, Michael R. Garcia, Jeffrey E. McClintock +3
We have obtained snapshot images of a transient X-ray source in M31 from Chandra ACIS-I and the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). The Chandra position…
Variable Star Candidates in an ACS Field of M31
Benjamin F. Williams
A search for variable stars is performed using two epochs of Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging data for a 9.28 square arcminute portion of M31.…
