Orbital Period Changes in IO Cep, IM Cep and TX Ari: Path to Masses of Distant Components
V. Bakış, Z. Eker, H. Bakış +7
Three Algol-type binary systems (IO Cep, IM Cep and TX Ari) showing cyclic orbital period changes are studied. The combination of time of minimum data from the ground-based observa…
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…
Long-term, orbital, and rapid variations of the Be star V923 Aql = HD 183656
M. Wolf, P. Harmanec, H. Božić +9
We present the latest results of a long-term observational project aimed at observing, collecting from the literature, and homogenising the light, colour, and spectral variations o…
