Optimization applied to selected exoplanets
(Springer, 2021)Transit and radial velocity models were applied to archival data in order to examine exoplanet properties, in particular for the recently discovered super-Earth GJ357b. There is however considerable variation in estimated ... -
The First Light Curve Solutions and Period Study of BQ Ari
(Springer, 2021)The first analysis of the photometric observation in BVR filters of a W UMa type binary system BQ Ari was performed. Light curve analysis was performed using Wilson-Devinney (W-D) code combined with a Monte Carlo (MC) ... -
Cylindrically symmetric unimodular f(R) black holes
(World Scientific Publishing, 2021)In this paper, we examine massless scalar field by using unimodular f(R) theory. It is taken into account unimodular and cylindrically symmetric spacetime which provides convenience in researching black hole. The field ... -
Semi-detached Algol type binaries with increasing orbital periods: Case studies of BD Vir, BO Gem, DG Lac, RW Cet, and RX Hya
(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 ... -
First photometric study of three eclipsing binary star systems: V495 Aur, V589 Aur and V478 Cam
(Elsevier B.V., 2023)The light curve solutions and orbital period analysis of V495 Aur, V589 Aur and V478 Cam eclipsing binary star systems are presented for the first time in this study. Transiting Exoplanet Survey Satellite (TESS) observations ... -
Comprehensive spectroscopic and photometric study of pulsating eclipsing binary star AI Hya
(Oxford University Press, 2023)The pulsating eclipsing binaries are remarkable systems that provide an opportunity to probe the stellar interior and to determine the fundamental stellar parameters precisely. Especially the detached eclipsing binary ... -
First Detailed Photometric Investigation on the Nature of Contact Binary System AA Cet
(Institute of Physics, 2023)The TESS light curve (LC) of the marginal contact binary AA Cet was analyzed simultaneously with the radial velocity and the orbital period (OP) change of the system was investigated. The physical parameters of the system ... -
Single-lined eclipsing binaries with δ Scuti components: GQ Dra, RR Lep, and TYC 683-640-1
(Oxford University Press, 2024)Eclipsing binaries with (a) pulsating component(s) are remarkable objects to investigate the evolution and structure of stellar systems. Detailed studies of such systems are also important to reveal their pulsation properties. ...
