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…
Investigation on the Orbital Period Variations of NN Ser: Implications for the Hypothetical Planets, the Applegate Mechanism and the Orbital Stability
Aykut Özdönmez, Hüseyin ER, İlham Nasiroglu
We present 36 new mid-eclipse times obtained between 2017 and 2023 using the T100 telescope in Turkey, extending the time span of the diagram to 25 years. Once again, these n…
