Proper motions of ROSAT discovered isolated neutron stars measured with Chandra: First X-ray measurement of the large proper motion of RX J1308.6+2127/RBS 1223
C. Motch, A. M. Pires, F. Haberl +2
The unprecedented spatial resolution of the Chandra observatory opens the possibility to detect with relatively high accuracy proper motions at X-ray wavelengths. We have conducted…
The XMM-Newton bright serendipitous survey. Identification and optical spectral properties
A. Caccianiga, P. Severgnini, R. Della Ceca +12
AIMS: We present the optical classification and redshift of 348 X-ray selected sources from the XMM-Newton Bright Serendipitous Survey (XBS) which contains a total of 400 objects (…
The XMM-Newton Serendipitous Survey V. Optical identification of the XMM-Newton Medium sensitivity Survey (XMS)
X. Barcons, F. J. Carrera, M. T. Ceballos +53
We present the XMM-Newton Medium sensitivity Survey (XMS), including a total of 318 X-ray sources found among the serendipitous content of 25 XMM-Newton target fields. The XMS comp…
Cyclotron modeling phase-resolved infrared spectroscopy of polars I: EF Eridani
R. K. Campbell, T. E. Harrison, A. D. Schwope +1
We present phase-resolved low resolution infrared spectra of the polar EF Eridani obtained over a period of 2 years with SPEX on the IRTF. The spectra, covering the wavelength rang…
Post common envelope binaries from SDSS. II: Identification of 9 close binaries with VLT/FORS2
M. R. Schreiber, B. T. Gaensicke, J. Southworth +2
The Sloan Digital Sky Survey turned out to be very efficient in identifying white dwarf/main sequence binaries (WDMS). The population of WDMS systems consists of wide systems whose…
The ultra-compact binary candidate KUV 23182+1007 is a bright quasar
John Southworth, A. Schwope, B. T. Gaensicke +1
KUV 23182+1007 was identified as a blue object in the Kiso UV Survey in the 1980s. Classification-dispersion spectroscopy showed a featureless continuum except for a strong emissio…
