Unravelling Mass Transfer in Algols from Surface Abundances. I. Z Vulpeculae
Ahmet Dervişoğlu, Simge Adalalı, Ferhat Güney +7
The photospheric abundance pattern of the components is a sensitive probe of mass and angular momentum transfer in Algols. With the aim to trace the evolutionary history and disclo…
Kilometre-scale Jovian moon characterized for a potential JUICE flyby
Juan Luis Rizos, Jose Maria Gomez-Limon, Yucel Kilic +51
Jupiter's irregular satellites are thought to be relics of early Solar System planetesimals. However, their small sizes, large distances from Earth and close angular proximity to J…
Shortterm optical variability of 4C 29.45
Aykut Özdönmez
We observed the flat-spectrum radio quasar 4C 29.45 in the BVRI optical bands for 39 nights from February 2022 to July 2022 with the T60 telescope at TÜBİTAK National Observatory (…
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…
Multi-Band Optical Variability of Blazar 1ES 2344+514 on Diverse Time-Scales
Aykut Özdönmez
This study presents the results of multi-band observations from 2022 to 2024 and Zwicky Transient Facility (ZTF) observations from 2018 to 2023, examining the flux variability of t…
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…
