Aims. Using the archival RXTE/ASM and SWIFT/BAT observations, the new orbital phases of type I outbursts of EXO 2030+375 are estimated. A possible correlation between the type II outburst and optical brightness variations is investigated.


Optical and X-ray outbursts of Be/X-ray binary system SAX J2103.5+4545
Kiziloglu, Ue.; Ozbilgen, S.; Kiziloglu, N.; Baykal, Altan (EDP Sciences, 2009-12-01)
Aims. The main goal of this study is to investigate the relationship between the optical and X-ray behaviours of the Be/X-ray binary system SAX J2103.5+4545.
Optical variabilities in the Be/X-ray binary system - GRO J2058+42 (CXOU J205847.5+414637)
Kiziloglu, Ue.; Kiziloglu, N.; Baykal, Altan; Yerli, Sinan Kaan; Ozbey, M. (EDP Sciences, 2007-08-01)
Aims. We present an analysis of long-term optical monitoring observations and optical spectroscopic observations of the counterpart to CXOU J205847.5+414637 (high-mass X-ray binary system). We search for variability in the light curve of Be star.
Activity from the Be/X-ray binary system V0332+53 during its intermediate-luminosity outburst in 2008
Caballero-Garcia, M. D.; Camero-Arranz, A.; Arabaci, M. Ozbey; Zurita, C.; Suso, J.; Gutierrez-Soto, J.; BEKLEN BARTO, Elif; Kiaeerad, F.; Garrido, R.; Hudec, R. (EDP Sciences, 2016-05-01)
Aims. We present a study of the Be/X-ray binary system V 0332+53 with the main goal of characterizing its behaviour mainly during the intermediate-luminosity X-ray event in 2008. In addition, we aim to contribute to the understanding of the behaviour of the donor companion by including optical data from our dedicated campaign starting in 2006.
An optical search for supernova remnants in the nearby spiral galaxy NGC 2903
SONBAŞ, EDA; AKYÜZ, AYSUN; Balman, Şölen (EDP Sciences, 2009-01-01)
Aims. We present the results of an optical search for supernova remnants (SNRs) in the nearby spiral galaxy NGC 2903.
Reanalysis of high-resolution XMM-Newton data of V2491 Cygni using models of collisionally ionized hot absorbers
Balman, Şölen; Gamsizkan, C. (2017-02-01)
Aims. We model spectral absorption features in data of the high-resolution XMM-Newton Reflection Grating Spectrometer.
