A Modified Kwee–Van Woerden Method for Eclipse Minimum Timing with Reliable Error Estimates
Galaxies, 2020 The Kwee–van Woerden (KvW) method used for the determination of eclipse minimum times has been a staple in eclipsing binary research for decades, due its simplicity and the independence of external input parameters, which also makes it well-suited to ...

The Astrophysical JournalWe present an analysis of eclipse timing variations in Kepler-451 using data spanning 2004–2024 from both ground- and space-based observations. Using two data sets, Data Set A (DS-A) and Data Set B (DS-B), we constructed updated O–C diagrams. By modeling

The Astrophysical JournalWe report a cyclic variation of the O − C diagram with a semiamplitude of 0.0033 days and a period of 1.05 yr for the pulsating eclipsing binary HZ Dra. The cyclic variation can be explained by the light travel-time effect via the presence of a close-in ...

MG1-1995959: An Eclipsing Binary Star with a Pronounced O’Connell Effect
The Astrophysical JournalMG1-1995959 is a short-period (∼0.586 day) eclipsing binary, exhibiting at times an extraordinarily large O’Connell effect (OE), for which this paper reports its discovery, time series photometry, and spectroscopic observation.

Long-term Orbital Period Variations of the Eclipsing Dwarf Nova HT Cas
The Astrophysical JournalWe 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 times obtained between 2015 and 2026 with archival data, we constructed an ...

An Eccentric Planet Orbiting the Polar V808 Aurigae
The Astrophysical JournalWe analyze 15 yr of eclipse timings of the polar V808 Aur. The rapid ingress/egress of the white dwarf and bright accretion region provide timings as precise as a few tenths of a second for rapid cadence photometric data.
