Context. The ratio of the first overtone (1O)/fundamental (F) periods of mixed-mode Cepheids that pulsate simultaneously in these two modes (F/1O) is metallicity-dependent. It can therefore be used to characterize the systems that host such variable stars. Aims. We want to take advantage of the F...

The Orbit of the New Milky Way Globular Cluster FSR1716 =VVV-GC05

Autor: Ramos, R.C. Minniti, D. Fernández-Trincado, J.G. Alonso-Garcia, J. Catelan, M. Gran, F. Hajdu, G. Hanke, M. Hempel, M. Diaz, E.M. Pérez-Villegas, A. Rojas-Arriagada, A. Zoccali, M.

We use deep, multi-epoch near-IR images of the VISTA Variables in the Via Lictea (VVV) Survey to measure proper motions (PMs) of stars in the Milky Way globular cluster (GC) FSR1716 = VVV-GC05. The colormagnitude diagram of this object, made by using PM-selected members, shows an extended horizon...
