Relative evolution of eclipsing binaries: A tool to measure globular cluster ages and He abundances
N. Cristi-Cambiaso, M. Catelan, A. A. R. Valcarce +1
Globular clusters (GCs) are among the oldest objects in the Universe for which an age can be directly measured, thus playing an important cosmological role. This age, on the other…

A study of nine extreme low mass ratio contact binary systems
E. Lalounta, P. -E. Christopoulou, A. Papageorgiou +2
Low mass ratio systems (LMR) are a very interesting class of contact eclipsing binaries challenging the theoretical models of stability. These systems are also considered possible…
