On the zero point constant of the bolometric correction scale

Eker, Zeki; Bakiş, Volkan; Soydugan, Faruk; Bilir, Selçuk (Oxford University Press, 2021)

Arbitrariness attributed to the zero-point constant of the V-band bolometric corrections (BCV) and its relation to ‘bolometric magnitude of a star ought to be brighter than its visual magnitude’ and ‘bolometric corrections ...
Semi-detached Algol type binaries with increasing orbital periods: Case studies of BD Vir, BO Gem, DG Lac, RW Cet, and RX Hya

Yıldırım, Muhammed Faruk; Soydugan, Faruk (Elsevier B.V., 2023)

This paper presents results from photometric investigations of five semi-detached binaries. Using the TESS and KEPLER (K2) databases, light curves of classical Algol systems BD Vir, BO Gem, DG Lac, RW Cet, and RX Hya were ...
Standard stellar luminosities: what are typical and limiting accuracies in the era after Gaia?

Eker, Zeki; Soydugan, Faruk; Bilir, Selçuk; Bakiş, Volkan (Oxford University Press, 2021)

Methods of obtaining stellar luminosities (L) have been revised and a new concept, standard stellar luminosity, has been defined. In this paper, we study three methods: (i) a direct method from radii and effective temperatures; ...
