A Few Years Later: Revisiting Period Variations of Eclipsing Binaries in the Northern Continuous Viewing Zone of TESS
T. Borkovits, T. Mitnyan, D. R. Czavalinga +1
In our previous analysis of the eclipse timing variation patterns of eclipsing binaries located in and near the Northern Continuous Viewing Zone (NCVZ) of the TESS space telescope,…
A Binary-Based Reassessment of the Age and Stellar Properties of NGC 7789 Using Twelve Binary Components
Kadri Yakut, Belinda Kalomeni, Saul Rappaport
We present a binary-based reassessment of the age of the intermediate-age open cluster NGC 7789, together with well-constrained stellar parameters for twelve components in six SB2…
A Deep Look into the Intermediate-Age Open Cluster NGC 2506: What Binary Systems Reveal About Cluster Distance and Age
K. Yakut, B. Kalomeni, S. Rappaport +1
Using high-precision observations from the space-based \textit{Gaia} and \textit{TESS} missions, complemented by ground-based spectroscopic data and multi-band photometric surveys,…
A novel approach to determining the age of stellar clusters: application to NGC 188
K. Yakut, B. Kalomeni, S. Rappaport
We present a new independent determination for the age of one of the oldest open clusters, NGC 188: Gyr. We utilize a novel approach where we jointly fit the radial…
