The Effects of System Interactions to the Natural Evolution of U Gem within the Context of X-Ray Data Analysis

Altan, Metin; Ayyıldız, O.; Hamza, C.; Kartal, S. Utku; Özkan, M. Türker (Astronomical Soc Pacific, 2011)

In this study, we have undertaken an analysis of Chandra data of the dwarf nova type cataclysmic variable U Gem during quiescence and outburst. The data of U Gem, number 647 and 3767, which were obtained by the Chandra ...
Natural Evolution of SS Cyg Based on an X-Ray Data Analysis at Very Short Periods

Ayyıldız, Ömer; Altan, Metin; Kartal, S. Utku; Hamza, Cansu; Özkan, M. Türker (Astronomical Soc Pacific, 2011)

We have carried out a Chandra data analysis of the prototype dwarf nova SS Cyg during quiescence and outburst. The SS Cyg data number 646 and 648 were obtained by the Chandra X-Ray Observatory on August 24, 2000 in quiescence ...
A study of RW Ursae Minoris shell

Esenoğlu, HH; Saygac, AT; Bianchini, A; Retter, A; Özkan, M. Türker; Altan, M (Edp Sciences S A, 2000)

We find an expansion parallax for the slow nova RW UMi (Nova Ursae Minoris 1956). A narrow-band H-alpha image shows that the diameter of the nova shell in 1995 was 2.94(+0.37)(-0.49) arcsec. We derive a distance of ...
