Based on its Hipparcos proper motion, we propose that the high-mass X-ray binary HD 153919/4U1700-37 originates in the OB association Sco OB1. At a distance of 1.9 kpc the space velocity of 4U1700-37 with respect to Sco OB1 is 75 km s(-1). This runaway velocity indicates that the progenitor of the compact X-ray source lost about 7 M-circle dot during the (assumed symmetric) supernova explosion. The systems kinematical age is about 2 +/- 0.5 million years which marks the date of the supernova explosion forming the compact object. The present age of Sco OB1 is less than or similar to8 Myr; its suggested core, NGC 6231, seems to be somewhat younger (similar to5 Myr) If HD 153919/4U1700-37 was born as a member of Sco OB1, this implies that the initially most massive star in the system terminated its evolution within less than or similar to6 million years, corresponding to an initial mass greater than or similar to 30 M-circle dot. With these parameters the evolution of the binary system can be constrained.

The X-ray spectral evolution of classical Nova V1974 Cygni 1992: A reanalysis of the ROSAT data
Balman, Şölen; Krautter, J; Ogelman, H (IOP Publishing, 1998-05-20)
We present a spectral analysis of the archival X-ray data of classical Nova V1974 Cygni 1992 (Nova Cygni 1992) obtained by the ROSAT Position Sensitive Proportional Counter (PSPC). The X-ray spectrum is fitted with a two-component model. The first component is a white dwarf atmosphere emission model developed for the remnants of classical novae near the Eddington luminosity. The model is used to fit the soft X-ray data in the similar to 0.1-1.0 keV range, where the bulk of emission is below 0.7 keV. The sec...
A STUDY OF THE LOW-MASS X-RAY BINARY DIP SOURCES XB 1916-053, XB 1323-619, X 1624-490 AND 4U 1746-371 OBSERVED WITH INTEGRAL
Balman, Şölen (IOP Publishing, 2009-07-01)
We detect dipping activity/modulations in the light curve of the four low-mass X-ray binaries in the 3-10 keV and 20-40 keV energy ranges. The spectral parameters derived from the fits to the International Gamma-Ray Astrophysics Laboratory data are consistent with hot coronal structures in these systems where we find a range of plasma temperatures 3.0-224.9 keV. The unabsorbed X-ray to soft gamma-ray fluxes between 4 keV and 200 keV are 5.9 x 10(-10) erg s(-1) cm(-2) for XB 1916-053, 3.3 x 10(-10) erg s(-1)...
Variations in the dip properties of the low-mass X-ray binary XB 1254-690 observed with XMM-Newton and INTEGRAL
Trigo, M. Diaz; Parmar, A. N.; Boirin, L.; Motch, C.; Talavera, A.; Balman, Şölen (EDP Sciences, 2009-01-01)
We have analysed data from five XMM-Newton observations of XB 1254-690, one of them simultaneous with INTEGRAL, to investigate the mechanism responsible for the highly variable dip durations and depths seen from this low-mass X-ray binary. Deep dips were present during two observations, shallow dips during one and no dips were detected during the remaining two observations. At high (1-4 s) time resolution "shallow dips" are seen to include a few very rapid, deep dips whilst the "deep" dips consist of many s...
The first resolved and detected classical nova shell in X-rays: The shell of Nova Persei 1901
Balman, Şölen; Ogelman, HB (IOP Publishing, 1999-06-20)
We present the ROSAT High-Resolution Imager data of the first resolved and detected classical nova shell in the X-ray wavelengths: the shell of Nova Persei 1901. We find that the X-ray nebula is composed of knots/clumps and has an elliptical shape with a total count rate of about 0.01 +/- 0.001 counts s(-1). We estimate that the spectrum is of thermal origin with a luminosity of similar to 8.0 x 10(31) ergs s(-1) and an X-ray temperature of similar to 2.0 x 10(6) K in the 0.1-2.4 keV energy range. The knots...
The XMM-Newton detection of extended emission from the nova remnant of T Pyxidis
Balman, Şölen (Oxford University Press (OUP), 2010-05-01)
We report the detection of an extended X-ray nebulosity with an elongation from north-east to south-west in excess of 15 arcsec in a radial profile and imaging of the recurrent nova T Pyx using the archival data obtained with the X-ray Multi-Mirror Mission (XMM-Newton), European Photon Imaging Camera (pn instrument). The signal-to-noise ratio in the extended emission (above the point source and the background) is 5.2 over the 0.3-9.0 keV energy range and 4.9 over the 0.3-1.5 keV energy range. We calculate a...
