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 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…
