Investigating the System Configuration of Kepler-451 through Orbital Period Variations: Dynamical and Magnetic Interpretations
Huseyin Er, Aykut Ozdonmez, M. Emir Kenger +5
We present an analysis of eclipse timing variations in Kepler-451 using data spanning 2004-2024 from both ground- and space-based observations. Using two datasets, DS-A and DS-B, w…
Long-term Orbital Period Variations of the Eclipsing Dwarf Nova HT Cas
Aykut Ozdonmez, Huseyin Er, Ilham Nasiroglu +7
We present a comprehensive analysis of the long-term orbital period variations in the short-period eclipsing dwarf nova HT Cas. By combining our new high-precision mid-eclipse time…
Intraday Optical Variability of BL Lacertae during its Highly Active 2020-2024 Phase
A. Takey, Ergün Ege, B. M. Mihov +12
We present an analysis of the intraday flux and spectral variability of BL Lacertae from 2020 September 30 to 2024 December 7, covering its highest recorded brightness and low, int…
Optical identification and follow-up observations of SRGA J213151.5+491400 -- a new magnetic cataclysmic variable discovered with SRG Observatory
Ş. Balman, I. Khamitov, A. Kolbin +21
We report results of optical identification and multi-wavelength study of a new polar-type magnetic cataclysmic variable (MCV), SRGA J213151.5+491400, discovered by Spectrum Roentg…
Probing Transit Timing Variations of Three Hot-Jupiters: HATP-36b, HATP-56b, and WASP-52b
E. Sonbas, N. Karaman, A. Özdönmez +5
We report the results of new transit observations for the three hot Jupiter-like planets HATP-36b, HATP-56b and WASP-52b respectively. Transit timing variations (TTVs) are presente…
A New Catalogue of Galactic Novae: Investigation of the MMRD relation & Spatial Distribution
Aykut Özdönmez, Ergün Ege, Tolga Güver +1
In this study, a new Galactic novae catalogue is introduced collecting important parameters of these sources such as their light curve parameters, classifications, full width half…
The Distances of the Galactic Novae
Aykut Özdönmez, Tolga Güver, Antonio Cabrera-Lavers +1
Utilising the unique location of red clump giants on colour-magnitude diagrams obtained from various near-IR surveys, we derived specific reddening-distance relations towards 119 G…
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…
