X-ray outburst of 4U 0115+634 and ROTSE observations of its optical counterpart V635 Cas

ROTSE IIId ( The Robotic Optical Transient Experiment) observations of the X-ray binary system 4U 0115+634/V635 Cas obtained during 2004 June and 2005 January make it possible, for the first time, to study the correlation between optical and type II X-ray outbursts. The X-ray outburst sharply enhanced after periastron passage where the optical brightness was reduced by 0.3 mag for a few days. We interpret the sharp reduction of optical brightness as a sign of mass ejection from the outer parts of the disc o...
X-ray flux and pulse frequency changes of three high mass X-ray binary pulsars: Vela X-1, GX 301-2 and OAO 1657-415
Inam, SC; Baykal, Altan (2000-01-01)
Using archival BATSE (Burst and Transient Source Experiment) 20-50 keV band X-ray flux and pulse frequency time series, we look for correlations between torque, luminosity and specific angular momentum for three high mass X-ray binary pulsars Vela X-1, GX 301-2 and OAO 1657-415. Our results show that there is no correlation between pulse frequency derivative and flux which may be an indication of the absence of stable prograde accretion disk. From the strong correlation of specific angular momentum and torq...

Arangdad, Kiarash; Yıldırım, Erol; Detwiler, Andrew; Cleven, Curtis D.; Burk, Christopher; Shamey, Renzo; Pasquinelli, Melissa A.; Freeman, Harold; El-Shafei, Ahmed (Wiley, 2020-07-01)
The photodegradation of irradiated PETG and PCCT model compounds namely Tm-CHDM-Tm and Tm-TMCD-Tm, where Tm refers to the methyl ester of terephthalic acid, CHDM refers to 1, 4-cyclohexanedimethanol, and TMCD refers to tetramethyl-1, 3-cyclobutanediol, was analyzed using X-ray photoelectron spectroscopy. Photodegradation products were characterized based on high resolution O(1s)x-ray photoelectron spectroscopy (XPS) spectra and the spectra of irradiated model compounds showed a decrease in the relative inte...
X-ray spectral and timing studies of the high mass x-ray binary pulsar 4u 1907+09
Şahiner, Şeyda; Baykal, Altan; Department of Physics (2009)
In this thesis, X-ray spectral and pulse timing analysis of the high mass X-ray binary pulsar 4U 1907+09, based on the observations with Rossi X-ray Timing Explorer (RXTE) and International Gamma-Ray Astrophysics Laboratory (INTEGRAL), are presented. INTEGRAL (October 2005 - November 2007) and RXTE (June 2007 - December 2008) observations confirm that the luminosity of the source is highly variable such that, flaring and dipping activities are observed. The results of time-averaged energy spectra of RXTE an...
