Rediscussion of eclipsing binaries. Paper XVIII. The F-type system OO Pegasi (2024)
Journal Article
Southworth, J. (2024). Rediscussion of eclipsing binaries. Paper XVIII. The F-type system OO Pegasi. Observatory, 144(1300),

OO Peg is a detached eclipsing binary system containing two late-A-type stars in a circular orbit with a period of 2.985 d. Using published spectroscopic results and a light curve from the Transiting Exoplanet Survey Satellite (TESS) we determine the... Read More about Rediscussion of eclipsing binaries. Paper XVIII.

Rediscussion of eclipsing binaries. Paper XVII. The F-type twin system CW Eridani (2024)
Journal Article
Overall, S., & Southworth, J. (2024). Rediscussion of eclipsing binaries. Paper XVII. The F-type twin system CW Eridani. Observatory, 144(1299),

CW Eri is a detached eclipsing binary system of two F-type stars with an orbital period of 2728 d. Light-curves from two sectors of observations with the Transiting Exoplanet Survey Satellite (TESS) and previously published radial-velocity data are a...

Looking for timing variations in the transits of 16 exoplanets (2024)
Journal Article
Yalçınkaya, S., Esmer, E. M., Baştürk, Ö., Muhaymin, A., Kutluay, A. C., Silistre, D. İ., …Yeşilyaprak, C. (in press). Looking for timing variations in the transits of 16 exoplanets. Monthly Notices of the Royal Astronomical Society, 530(3), 2475–2495. https://doi.org/10.1093/mnras/stae854

We update the ephemerides of 16 transiting exoplanets using our ground-based observations, new TESS data, and previously published observations including those of amateur astronomers. All these light curves were modeled by making use of a set of quan... Read More about Looking for timing variations in the transits of 16 exoplanets.

Observational mapping of the mass discrepancy in eclipsing binaries: Selection of the sample and its photometric and spectroscopic properties (2024)
Journal Article
Tkachenko, A., Pavlovski, K., Serebriakova, N., Bowman, D. M., IJspeert, L., Gebruers, S., & Southworth, J. (2024). Observational mapping of the mass discrepancy in eclipsing binaries: Selection of the sample and its photometric and spectroscopic properties. Astronomy & Astrophysics, 683, Article A252. https://doi.org/10.1051/0004-6361/202347793

Context. Eclipsing spectroscopic double-lined binaries are the prime source of precise and accurate measurements of masses and radii of stars. These measurements provide a stringent test for models of stellar evolution that are consistently reported...

Rediscussion of eclipsing binaries. Paper XVI. The δ Scuti / γ Dor hybrid pulsator GK Draconis (2024)
Journal Article
Southworth, J. (2024). Rediscussion of eclipsing binaries. Paper XVI. The δ Scuti / γ Dor hybrid pulsator GK Draconis. Observatory, 144(1289),

GK Dra is a detached eclipsing binary system containing two early -F stars, one evolved, in an orbit with a period of 9974 d and a small eccentricity. Its eclipsing nature was discovered using Hipparcos data, and pulsations were found in follow-up gr... Read More about Rediscussion of eclipsing binaries. Paper XVI.
