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…
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…
Empirical Bolometric Correction Coefficients for Nearby Main-Sequence Stars in Gaia Era
Z. Eker, F. Soydugan, S. Bilir +6
Nearby detached double-lined eclipsing binaries with most accurate data were studied and 290 systems were found with at least one main-sequence component having a metallicity $0.00…
Investigation of near-contact semi-detached binary W UMi through observations and evolutionary models
Faruk Soydugan, Esin Soydugan, Fahri Aliçavuş
W UMi is a near contact, semi-detached, double-lined eclipsing binary star with an orbital period of 1.7 days. Simultaneous analysis of new BVR multi-color light curves and radial…
Interrelated Main-Sequence Mass-Luminosity, Mass-Radius and Mass-Effective Temperature Relations
Z. Eker, V. Bakis, S. Bilir +7
Absolute parameters of 509 main-sequence stars selected from the components of detached-eclipsing spectroscopic binaries in the Solar neighbourhood are used to study mass-luminosit…
The Galactic Kinematics of Cataclysmic Variables
T. Ak, S. Bilir, A. Özdönmez +5
Kinematical properties of CVs were investigated according to population types and orbital periods, using the space velocities computed from recently updated systemic velocities, pr…
Effective Temperatures of Selected Main-sequence Stars with Most Accurate Parameters
F. Soydugan, Z. Eker, E. Soydugan +6
In this study, the distributions of the double-lined detached binaries (DBs) on the planes of mass-luminosity, mass radius and mass-effective temperature have been studied. We impr…
The Spectroscopic Orbits of Three Double-lined Eclipsing Binaries: I. BG Ind, IM Mon, RS Sgr
V. Bakis, H. Bakis, S. Bilir +7
We present the spectroscopic orbit solutions of three double-lines eclipsing binaries, BG Ind, IM Mon and RS Sgr. The first precise radial velocities (RVs) of the components were d…
