Kinematics of Cataclysmic Variables in the Solar Neighborhood in the Gaia Era
R. Canbay, T. Ak, S. Bilir +2
Using high-precision astrometric data from Gaia DR3 and updated systemic velocities from the literature, kinematical properties of cataclysmic variables (CVs) were investigated. By…
A Silent Revolution in Fundamental Astrophysics
Z. Eker, F. Soydugan, V. Bakis +2
Arbitrariness in the zero point of bolometric corrections is a nearly century-old paradigm leading to two more paradigms. "Bolometric corrections must always be negative," and "bol…
Standard stellar luminosities; what are typical and limiting accuracies in the era after Gaia?
Z. Eker, F. Soydugan, S. Bilir +1
Methods of obtaining stellar luminosities (L) have been revised and a new concept, standard stellar luminosity, has been defined. Among the three methods (direct method from radii…
The Transient Ultra-luminous X-ray Source, ULX-4, in M51
S. Allak, A. Akyuz, İ. Akkaya Oralhan +6
We present the results of a temporal and spectral analysis of the transient source ULX-4 in the galaxy M51. The data used were drawn from Chandra, XMM-Newton and Swift-XRT archives…
On the Zero Point Constant of the Bolometric Correction Scale
Z. Eker, V. Bakis, F. Soydugan +1
Arbitrariness attributed to the zero point constant of the band bolometric corrections () and its relation to "bolometric magnitude of a star ought to be brighter than it…
Kepler Binary Stars in NGC 6819 Open Cluster: KIC 5113146 and KIC 5111815
E. Soydugan, F. Alicavus, F. Soydugan +1
In this study, investigation of two double-lined binary stars KIC 5113146 and KIC 5111815 in NGC 6819 is presented based on both photometric and spectroscopic data. Simultaneous an…
